Leveraging a Flexible Intellectual Property Policy to Bring Student Innovation to Market

Abstract

An engineering school at a primarily undergraduate, public, regional university in the Midwest uses a liberal intellectual property policy in conjunction with hands-on design and build projects in multiple classes to enable students to reap the rewards of their product ideas. The university's intellectual property policy contains two interesting facets that pertain to student innovation. First, students own their ideas. If a student proposes an idea to work on in a course then the student owns the resulting intellectual property as long as the student does not use more resources than the typical project in the class. The other interesting part of the policy is the concept of the innovation committee. The innovation committee, consisting of faculty and administrators, reviews intellectual property submitted by faculty and students. Faculty are required to submit their patentable ideas but for students it is optional. If the committee decides the idea has commercial potential, then the student negotiates a financial agreement to move the product forward through the patent process to market. The innovation committee usually offers money to obtain a patent, create a more refined prototype or help in licensing the technology. In return the student inventors agree to pay the committee a percentage of profits or give the committee part ownership in the resulting company. Examples of several student projects that used the assistance of the innovation committee will be described in the paper.

Background

Grand Valley State University (GVSU) is a public primarily-undergraduate regional comprehensive university serving over 26,000 students. The university was founded in 1960. Today the Mission of the school is “Educating students to shape their lives, their professions, and their societies. The university contributes to the enrichment of society through excellent teaching, active scholarship, and public service”. To fulfill the pubic service aspect of the mission statement, the School of Engineering (SOE) was established in 1980 to supply local industry with engineers capable of assuming leadership roles. Since it founding the SOE has been able to expand and build two buildings with the financial support of local industry. In the past decade, the forces of globalization and international competition have challenged manufacturing companies of all sizes that have traditionally supplied much of the economic vitality to the region.

At the same time the growth and maturation of GVSU required the formulation of a formal intellectual property policy. A committee of faculty and administrators established the policy 20041. One of the guiding principles of the policy was the idea that the discoveries made at the university should pushed into the market to benefit the local economy. The salient points of the policy are summarized below.

1. The university may license or assign intellectual property to external entities for further development and commercialization in exchange for a return on resulting revenues. The university and creator (inventor) shall divide the return on resulting revenues using one of the two formulas as follows:

2. The University and the creator divide the gross revenue 70% to the university and 30% to the creator but the University assumes the expenses related to legal protection, marketing and commercialization and licensing and other transactional expenses related to the Intellectual property; or,

3. The university and the creator divide the net revenue 50% to the university and 50% to the creator but the university first recovers its expenses related to legal protection, marketing and commercialization and licensing and other transactional expenses related to the intellectual property.

4. If the university decides not to protect or license the intellectual property, or subsequently decides to not pursue commercialization of the Intellectual Property it may be reassigned to the creator(s), upon request. The return to the university for a reassignment of ownership will be ten percent (10%) of the net revenue generated by the intellectual property.

An “Innovation” committee was formed to advise the university about which intellectual property is worth protecting and licensing. The committee is made up of faculty and administrators. The committee is chaired by the executive director of the West Michigan Science & Technology Initiative (WMSTI), an organization dedicated to developing intellectual property from its member organizations in the region.

Student Involvement

The faculty supported the policy because they perceived the policy to be more generous than the policy of other research orientated universities in the area and geared toward the economic development of the local region. However the founding of the entrepreneurship minor and the product development major in engineering brought the question of student generated intellectual property to light. The entrepreneurship minor and the product development major were both initiated in 2004. Both programs encourage students to develop intellectual property as a part of the academic experience. Eventually, how to handle student generated intellectual property ended up as the topic of a meeting with the president of the university. The president, the Dean’s of the business school and the engineering school, the faculty involved in the entrepreneurship minor and the product development major and the executive director of WMSTI were all in attendance. The issue of contention was does the university have a claim to some ownership of student intellectual property generated to fulfill course requirements. Widely divergent opinions and arguments were presented. The director of WMSTI argued that the university was entitled to part ownership of any intellectual property generated in the classroom or laboratory. The faculty countered that the students could not be treated like employees of the university. The students had paid for access to the faculty and laboratories as part of their tuition. The Deans did not express any opinions.

In the end the president brokered a compromise with the two unique points. First, students own their ideas. If a student proposes an idea to work on in a course then the student owns the resulting intellectual property as long as the student does not use more university resources than a typical project in the class. Second students may choose to present their ideas to the innovation committee to seek support to commercialize their ideas. When students seek such support from the innovation committee they are treated the same as faculty. This policy has lead students to propose more than half of all of the ideas submitted to the innovation committee.

Policy in Practice

As with most policies, the implementation details are as important as the statement of the policy. For the student intellectual property policy, the faculty teaching the courses that give rise to the intellectual property are key to the policies implementation. The faculty identify student projects with potential intellectual property and advise students of their options. In general students can do the following:

Try to commercialize their intellectual property on their own.

Apply to the innovation committee for support to commercialize their ideas.

Do nothing with their intellectual property.

Each option has different rewards and obstacles. The first option offers the highest financial rewards but has significant obstacles in terms of the student’s ability to martial financial, time and business resources. This option also has the most risk associated with it. The third option has no rewards and no risk. Many engineering students are attracted second option because they can attempt to bring their product to market while minimizing their personal risk and time commitment. In addition the engineering students desire a patent with their name listed as inventors almost as much as financial rewards. Students desire patents for the prestige of having a patent and as an aid to securing an attractive job offer. The risks of applying to the innovation committee include getting involved with a slow moving university bureaucracy, meeting the committee’s demands for financial rewards and the possibility that university will take 10% of the net revenue generated even if the innovation committee rejects the idea. Weighing the risks and opportunities of the different options is an important learning experience for the students.

The students begin the process of applying to the innovation committee by filling out an Invention Disclosure Form (IDF). The IDF requires the student to describe the invention, the advantages of the invention compared to products available and the commercial applications of the invention. The IDF form is shown in the attached appendix. Some faculty require students to fill out the form as part of the required course work. Students then have the option of submitting the form. Other faculty require students to draft patent claims and include them in the form. The innovation committee rates each idea using on its financial viability, commercial viability, technical viability and the ideas alignment with the university’s mission. The criteria and rating systems are shown in tables 1-4.

Table 1. Criteria and rating system for judging the financial viability of an idea.

Table 2. Criteria and rating system for judging the commercial viability of an idea.

Table 3. Criteria and rating system for judging the technical viability of an idea.

Table 4. Criteria and rating system for judging how well an idea aligns with the mission of the university.

The students know these criteria and can use this information when they decide whether or not to apply to the innovation committee for support. The criteria are used as guidelines only. There are no minimum point requirements that an idea must achieve to receive support. The committee recommends which ideas to support and the head of the committee negotiates with the inventor and the university to reach a specific agreement.

Undergraduate Project Examples

The undergraduate engineering curriculum includes projects in multiple courses. The patent project work often occurs in one or more courses. In some cases the students that own the idea are not the ones who work on it in other courses.

The Trap Thrower Invention

The trap thrower invention was conceived by two students working on a design and build project for a junior level engineering class entitled “Manufacturing Control Systems”. One student was on GVSU’s rifle team. He desired to have a trap thrower that could be programmed to throw a different number of traps in different patterns. In addition he thought that a setting for throwing a random number of traps in a random pattern would be useful. The students designed, built and financed the first prototype. The students then applied to the innovation committee for support. The committee believed that the concept was not only patentable but also technically, financially and commercially feasible. The committee recommended that a provisional patent be filed and that a second, more refined prototype be constructed to better demonstrate the benefits of the concept to companies that could potentially license the technology. The university agreed to finance the provisional patent and the construction of the second prototype. The students built the second prototype to fulfill the project requirement for a senior level course entitled “Advanced Product Design”. The university is currently negotiating with a manufacturer to license the technology. Figure one shows a rendering of the product.

Figure 1. A rendering of the trap shooter product.

The Pedal-Pro Product

The need for the pedal-pro product was discovered in a graduate engineering design course. Unfortunately a marketable solution was not found. A student in the graduate class was a competitive bicyclist and he desired a product to measure, graph and analyze the torque produced by each leg as a function of the crank angle. Similar products on the market could not measure the torque produced by each leg separately. In addition many of the competitive products were designed for use on stationary bikes. A student in the advanced product design class decided to take up the challenge of creating a marketable product to meet the need. When the student’s solution proved to be simple, low-cost and accurate, he applied to the innovation committee for help to bring the device to market. Unlike the trap thrower product, the student desired to form a company to manufacture and market the product. In this case the innovation committee decided to fund the provisional patent and use their contacts to help the student form the company and refine the design of the product. The company, Magnum Engineering, has been formed and is now working to bring the product to market with the help of an undergraduate senior capstone project team. The product should be ready for market in the Fall of 2008.

The Lean Wheel Chair

In the summer of 2007 the founder of MOVE International, a non-profit organization dedicated to helping special needs children achieve dignity, approached the engineering school in search of a device to transform a powered wheel chair into a training aid. She wanted a device that would allow a child to control the movement of a powered wheel chair by leaning. The act of leaning helps the children learn to control the muscles in their trunk. This is the first step in achieving mobility. In the fall of 2007 a team in the new product development class took on the challenge. The team worked with students and staff at a local school for special needs students to develop and refine a solution. The prototype was well received and the students were encouraged to think about the best way to bring their product to market. The team decided to finance the prototype without the help of the engineering school or MOVE international in order to preserve their claim to the resultant intellectual property. The team is now deciding if they want to apply to the innovation committee for support.

Graduate Project Example

During the fall of 2007 graduate students in EGR 604 - Implementation designed products with the intention of patenting the results using the universities system. From the outset the students were tasked with identifying common problems, irritations, and issues. From these the class of 16 generated over 50 potential invention opportunities. These were narrowed down and concepts were generated for a smaller set. Students were asked to investigate the concepts to determine if similar products or patents existed. Eventually the class identified three areas without prior art that had market potential. Students were then tasked with producing working prototypes, preparing a patent application and an application for the university IP committee.

One of the three projects involved automotive speed bumps. Speed bumps are designed to manage traffic patterns by encouraging drivers to slow down and avoid jarring their cars. These are commonly made using a mound of paving material laid across a roadway. Although simple in concept they have a number of limitations. The use of paving materials requires special planning and labor to install and substantially more labor to remove. The performance is highly dependent on geometry, but this can be hard to control. Even slow drivers must endure the full motion of the bump, albeit at a slower pace. An alternate method for constructing speed bumps was devised that would use a non-Newtonian fluid housed inside a rubber bladder. The rubber bladder would stretch across the road, and normally hold the fluid in a mound shape. When deformed by a car tire there would be resistance to the deformation that is a function of the shear rate. In other words, driving slowly would result in a much lower force, and less lifting of the vehicle. Moreover, these speed bumps could be made in configurations that are portable and reusable. For example, for special events the bumps could be deployed in parking lots to slow cars. After the event the bumps can be collected and used elsewhere. Moreover the geometry and materials of the bumps could be varied so that they are tuned for higher/lower speeds and more or less tolerance for violations.

Discussion

The liberal intellectual property policy that is applied to student work has many advantages for the university as well as the students. The university advances its mission by commercializing products that will yield economic and social benefits to the local community. The School of Engineering is benefiting from engaged students who have confirmation of the worth and utility of the knowledge and skills they have gained through their education. Today many students aspire to graduate with a patent. Students gain experience with real-world design problems and the challenges of commercialization. For many students this is the first time they have considered becoming an entrepreneur. Although the intellectual property policy is young, initial results are encouraging.

GRAND VALLEY STATE UNIVERSITY

INVENTION DISCLOSURE
Cover Sheet for Inventors

An invention disclosure should be made when some new and useful idea has been conceived or developed at GVSU, or when a GVSU employee or student has obtained unusual, unexpected, or unobvious research results that can be utilized by someone to enhance economic development in west Michigan.

This Invention Disclosure Form (“IDF”) will enable evaluation of your idea to determine (a) its patentability and (b) its potential for commercial value. An apparatus, a composition of matter, a method of doing something (including business methods), or any improvement in these things can be patentable.. An invention can also have commercial value, even if it is not patentable. The invention should be clearly described so that someone having knowledge in your particular field can understand its technical merits, its usefulness, and possible practical applications. Information that helps an evaluator appreciate the invention will increase its ultimate chances for successful patenting and possible commercialization. This is the goal in Section 1-4 of the attached IDF.

The remainder of the IDF covers certain general issues that need to be considered with every invention. The first is public disclosure of the invention (Section 5), because such disclosure places severe limitations on available patent protection. Non-confidential disclosure of an invention (to people outside of GVSU) may trigger a one year “grace” period within which a U.S. patent application may be filed. If an application is not filed within that time, U.S. law prevents you from ever obtaining patent protection for the disclosed invention. The patent laws of most other countries are even stricter: the right to patent protection is lost immediately upon public disclosure unless a patent application was filed prior to such disclosure. Thus, to secure the availability of worldwide patent protection, it is important that an IDF be submitted for timely review so that an evaluation can be done in order to timely file a patent application before public disclosure occurs.

Determining ownership and licensing rights in the invention is addressed in Section 6. Identification of the financial support used during the development of the invention helps determine whether contractual obligations exist with research sponsors or collaborators.

The final issue addressed by the IDF is the identification of the individuals who contributed to the development of the invention (Section 7). Please note that these individuals may not meet legal criteria for inventorship. Inventorship is determined/clarified by a patent counsel at the time a patent application is filed. Only the person completing the IDF and the Department Head need to date and sign this form.

Please use the backs of the IDF pages or appended sheets if space is insufficient. You are encouraged to include additional comments that you or the other contributors may have regarding the invention.

For advice on completing the disclosure form or for additional information, contact Linda Chamberlain at 331-5859 or chambeli@gvsu.edu.

Preparing for Electronic Textbooks

 

 

Abstract

 

Electronic copies of books are becoming increasingly common. Examples of these include noneditable PDF files, or fully editable books based on the Wiki model17. Electronic books are well suited to engineering; they allow very fast updates, they are easy to access, they do not require the bulk of paper, they are easily searchable, and they allow multiple/alternate sources. So, this begs the question, why are there so few electronic books in use in higher education? In part, this is because many of the commercial books are not available electronically. Although some publishers are exploring ways to make their collections available electronically these efforts are still in their infancy.

 

However, a larger puzzle is in the step away from paper to purely electronic media. For example, consider the following problems. How do you write notes or slip a page into a fixed PDF file? Is the document you are viewing on your machine or on the network? Who can change the document? What happens if somebody changes a homework problem after it was assigned? Etc. Assuming that the future of the electronic book is on-line there are currently two popular models. In the Distribution model there are a small number of authors and editors who control and distribute a fixed or editable format for the book. This model most closely resembles the current publishing model. In the open model the book would be on a Wiki or Content Management System (CMS) where multiple editors and contributors could freely change it. The open model has great potential to generate excellent electronic books, but it adds some new considerations not previously encountered. The paper discusses some of the anticipated issues such as multiple versions, various notations, vandalism, and editing rights for students and faculty. In addition a set of features are proposed for the purpose of fueling discussion.

 

The Current Situation

 

Our students make extensive use of textbooks that are printed on paper. They also spend a significant amount of time carrying bags full of paper. This flies in the face of many predictions that paper would all but disappear by the millennium. Although paper has some clear benefits, it is worth asking why electronic books are not more common given laptops and other portable electronic devices.

 

Electronic publishing does exist but it is somewhat limited. There are an ever increasing number of free electronic books available on the internet. Most of these are in PDF format, making them easy to read and search while keeping the overall file size relatively small. Some older books are stored as scanned images, preventing searches and requiring much larger file sizes, but these are still relatively small on a modern hard drive. However, publishers are reluctant to release their mainstay titles in electronic formats for fear of the copying like that seen in the music industry.

 

There have been many false starts as the commercial publishers have tried to join the electronic world. Some of these include the efforts listed below. It is worth noting that most of their efforts increase the cost for the materials, do not relinquish control of content, and do not take full advantage of modern computers.

• including supplemental CDs with additional chapters, solutions, videos, software, etc.

• time limited access to on-line resources.

• electronic only books where students buy access for a semester.

• ebook readers and/or software that lock in the electronic books.

• unrestricted ebooks bundled with regular ebooks. The author recalls a bundled supplement to a controls book using Mathcad in 1995.

• on-line databases with limited printing capabilities.

 

For a number of reasons the free-open-source (FOS) community is growing away from the traditional publishers and starting to develop materials themselves. The most notable case is the emergence of wikipedia.org from a mere curiosity a couple of years ago, to a major competitor to the Encyclopedia Britannica1. Other publishers expect to confront similar situations soon from groups focused on textbooks2,3.

 

The Good and Bad of Paper

 

Most of us appreciate the value of looking through a library to find information. Having a set of books on related topics grouped on a shelf creates knowledge proximity better than a search engine4 could. A few minutes of flipping can give a bird’s eye view of a topic, and a table of contents and index can give easy access to specific information very quickly. Moreover the books on the shelf are generally trustworthy because they have been reviewed and edited by qualified professionals.

 

By their very nature paper bound books have some constraints imposed by the fact that they must be edited, printed and sold within a reasonable time frame. In summary these can be listed as,

• books are prepared to address a topic - the emphasis is on ‘a’

• the material in a books if often aimed at a particular knowledge level

• books must be printable within limits (length, size, features, colors, etc)

• books can be augmented with media (such as CDs)

• a textbook should cover a topic in a linear order that builds in complexity

• books are controlled by a single author with the support of highly qualified reviewers and editors

• the cost is higher if the book is more complex or has a small circulation

 

Ironically it is worth noting that all modern books are typeset in software and exist in an electronic form before they are every printed. It would actually be much easier, but less lucrative, if the publishers dispensed with the printing process.

 

 

New Developments

 

The concept of electronic publishing and distribution is not new and is destined to happen eventually. Some of the issues surrounding electronic publishing are;

 

• The number of electronic books available on the internet has blossomed. One of the earliest pioneers of internet publishing is Project Gutenberg that specialized in out of copyright classics5. More recently there have been a proliferation of books that are more recently out of print6, or self published7.

 

• A number of tools already exist for collaborative publishing. For example electronic books on the internet can use the Gnu Free Documentation License (GFDL)8. For example a book originally released in English9 under this license was then translated to Dansk10.

 

• Many individuals are concerned that if the publishers dominate the transition to electronic books there will be a widespread use of Digital Rights Management (DRM) protection to prevent copyright infringement. There is major design that DRM is intended to help protect content owners, it is very harmful to the rights of the general public. It is also expected to have numerous consequences for libraries11.

 

• Collaborative publishing models seem to have captured the imagination and spirit of those outside the academic world. Wikipedia is an excellent example, allowing individuals (not verified experts) to contribute and edit articles. The larger community then reviews and vets the articles for accuracy and impartiality. Early concerns that the site would be overrun with vandalism and ‘flame wars’ have been largely unfounded.

 

• Previously figures and equations were stored as bit mapped images that were very difficult to edit. The Internet standards groups have been adopting new standards that allow easier editing of figures with SVG12 and equations with MML13.

 

• Content Management Systems (CMS) have been developed for cooperatively developing complex technical documents using networked environments. Some of these include Drupal14,15. In many ways these are more like distributed work processors, as opposed to the distributed web editors of the wiki models.

• Other computing models are emerging such as portable computing applications using flash drives. For example one that applies to this work is a portable wiki environment that includes MML and SVG editing capabilities running on a web page with AJAX - no additional software is needed on the host computer, beyond the browser16. Another similar software package is Doxwiki.

 

 

A Sample Vision

 

Technologically we are ready for electronic books in the classroom. The major barrier at this point is a proven model that others can reuse. A crude example model of use of the book in a course is outlined below.

1. Before the course the instructor identifies the text sections and depth that she/he wants to use for the standard student. An instructor could even elect to provide a set of problems to solve for the semester, and then references to course material to help the students solve the problems.

2. At the beginning of a course each student downloads the textbook master copy to their flash drive, or they configure an on-line site.

3. As the semester progresses students are guided through the book at a high level. If a particular student needs more knowledge about a particular topic they pursue the details they need by 'drilling down' in the text or on the Internet. It would also be possible to provide alternate materials for concrete vs. abstract learners.

4. Throughout the semester students make their own notations in the textbook that only they can see. They may also choose to submit suggestions or corrections to the master version. If approved the corrections will be available to other students immediately.

5. By the end of the course each student has a view of the book that is highly individualized.

6. Students can reconcile their changed book with the on-line book at any time. This would have value by allowing them to import corrections and improvements since the initial creation.

 

One possible use is illustrated in Figure 1. Essentially an instructor would assemble a (linear) course outline using available resources. Some of the resources would be considered core and simply copied into the course outline. Others may be left as hyper links for a variety of reasons such as copyrights, the material changes frequently, the material is review/tutorial in nature, etc. The students would then take a copy of the course outline made by the instructor and follow/modify as they see fit. It is also possible for the students and instructor to submit changes/additions to the sources, based upon their local changes. The sources may also be maintained by others outside the academic system as appropriate.

 

While the model presented appears to only consider free sources, it is possible for this model to be of value for commercial publishers. This is important because commercial publishers do help provide additional motivation for developing high quality books, services, and information.

Issues to be Resolved

 

There are a number of issues as classified below.

 

Essential

- Identify software that requires little or no client end installation/maintenance.

- Allow dynamic on-line editing of equation (MML or Latex) and image formats (SVG) in documents.

- Establish permissions/policies for public and course based book editing.

- A clear model to emphasize the value for instructors is critical to the adoption of the model.

- The model should allow non-linearity including linking to other documents and media types.

- Allow the material to be constructed in alternate ways so that it is not driven by the body of the writing.

 

Nice to Have

- Identify ways to allow portable electronic books that vary from the master copy, but refer back to it.

- Explore unique technologies that allow locally hosted Wiki's (or CMSs) such as doxwiki, dokuwiki, tiddlywiki.

- A policy that encourages the uniformity of notations and formats without forcing a monoculture to develop.

- Use of tools such as writely to support collaborative work.

- Develop a commercial model for publishing to reward authors, editors, and distributors.

- Concurrent development software may provide a tool for resolving parallel changes in the book. One such system long in use for software is the Concurrent Version System (CVS).

 

The Next Step

 

The author is progressing to develop identify and test software to implement the electronic textbooks. It is hoped that others would be able to provide helpful input to steer this process.
