INTRODUCTION

I, Lance Rake, have been retained by counsel as an expert witness to provide 

my opinion on the alleged infringement of Plaintiffs Hangzhou Chic Intelligent 

Technology Co. and Unicorn Global Inc.’s (collectively “Hangzhou”) U.S. Patents 

D737,723, D738,256, D784,195, and D785,112 (“the Patents-In-Suit”) by 

Defendant Gyroor-US. 

I have set forth my academic and professional qualifications and relevant 

experience in the Background and Qualifications section of this report, and have 

attached a copy of my curriculum vitae as Exhibit 1, which contains further details 

on my education, experience, publications, and other qualifications for rendering an 

expert opinion here. 

In forming the opinions, I express in this report, I considered materials 

provided by counsel, and the references discussed in this report. Further, I relied on 

my own knowledge, training, and over 45 years of experience in designing, 

developing, teaching, and consulting in the industrial design industry. I reserve the 

right to update and revise my opinions and conclusions, for example, should any 

additional data or information become available to me. 

I am compensated at my standard hourly rate of $300 per hour for the time I 

spend on this matter. My compensation is not related in any way to the outcome of 

this proceeding, and I have no other interest in this proceeding.

BACKGROUND AND QUALIFICATIONS

I am an industrial designer and a design researcher and educator. I have a 

Bachelor’s Degree in Industrial Design from the University of Kansas, received in 

1974, and a Master’s Degree in Product Design from North Carolina State

University, received in 1982. According to a 2004 brochure from the Industrial 

Designer’s Society of America (IDSA):

Industrial design is the profession that determines the form of a manufactured 

product, shaping it to fit the people who use it and the industrial processes that 

produce it.... Preparation for practicing Industrial Design requires a baccalaureate 

degree in that field. Industrial design links knowledge about technology and the 

visual arts with knowledge about people. In addition to a thorough understanding 

of the physical sciences, engineering principles, ergonomics, aesthetics, and 

industrial materials and processes, Industrial Designers should be well-grounded in 

the social sciences, such as psychology, sociology and anthropology, and the 

communication arts, such as photography, video, print and electronic media.

I have worked as an industrial designer continuously for 46 years since 

receiving my undergraduate degree in 1974. In 1980, I began my career as a fulltime faculty member at various universities. From 1980 to 1984, I was an Assistant 

Professor of Industrial Design at Auburn University. From 1985 to 1986, I was the 

Product Design Course Supervisor (Department Chair) at UNITEC Institute of 

Technology in Auckland, New Zealand. 

I then returned to the United States and began teaching at the University of 

Kansas in 1987 as an associate professor. I am presently a full professor with the 

University of Kansas, and my formal title is Professor of Design, School of 

Architecture & Design. Also while at the University of Kansas, I was the Founding 

and Acting Director of the Center for Design Research from 1991-2005. My 

responsibilities at the University of Kansas require me to direct 40% of my time to 

creative activity and research.

For 16 years, from 2000-2016, I served as a design consultant to Infusion 

Design. My creative activity there centered on collaborative design work in the 

transportation and consumer products industries. As a practicing professional, I 

have designed commercial and consumer products, transportation interiors, 

packaging, and exhibits for over 80 different clients. I have been retained to create

designs for manufactured products that contain metal components, including 

commercial electronics, consumer products, lawnmowers, and airplane and boat 

interiors.

As a design practitioner and educator, I have conducted and/or directed 

research into the study of markets from a product design perspective, as well as 

researching product usability. I have given presentations on design at several 

institutions around the world. Topics include ergonomics, design education, design 

practice, and contemporary issues in the practice of industrial design. 

I have 16 invited international presentations and lectures on various design 

topics. My work has been supported by over 25 internal and external grants. In the 

last five years over 30 design websites and blogs have profiled my work, and three 

recent books feature my design work. Professionally, I have worked on hundreds of 

designs for over 90 unique clients in the past 44 years. A list of my design-related 

research, publications, speaking engagements, and professional clients can be found 

in my attached curriculum vitae. 

My work has been featured in numerous articles and texts, including the text 

“Think Wrong,” relating to design innovation and processes. The book features a 

story about my design process, focusing on my philosophy of working with and 

manipulating physical materials early in the design process to develop prototypes 

early in the design process. 

I was the Founder & Acting Director of KU’s Center for Design Research, 

from 1994-2006. The CDR was created to focus our graduate program in order to 

realign research efforts in collaboration with regional and national industry partners. 

I was solely responsible for the effort, establishing an effective design team, securing 

funding and research projects from industry partners including Learjet, Bass Pro 

Shops, and Hewlett-Packard. 

Since 2010 I gave designed a number of skateboards, longboards, stand-up

paddleboards and bicycles as part of my research at the University of Kansas.

In my role as a professor, I have taught an Industrial Design Studio course 

nearly every semester since approximately 1980, which is a product-focused course. 

As part of the Industrial Design Studio, I have supervised groups of students 

developing a variety of different products. 

I have served as an expert witness since approximately the year 2000, and 

have been retained as an expert witness in approximately thirty cases, including 

cases involving design patents and/or trade dress claims. I received an IDSA 

Continuing Education Certificate entitled “How to Serve as an Expert Witness in 

Design Patent Litigation” in 2008. Many of the cases for which I have been retained 

have involved issues relating to alleged design patent infringement.

I am an inventor on 12 design and utility patent applications, including U.S. 

Patent No 7,900,781 for “Storage System,” U.S. Patent No. 5,490,676 for “Playing 

Cards with Gripping Surface,” U.S. Patent No. D600,928 for “Step Stool,” and U.S. 

Patent No. 6,820,286 for “Protective Mask.”

In Fall 2012, I was awarded a sabbatical to teach and conduct design research 

at the Industrial Design Centre at the Indian Institute of Technology-Bombay in 

Mumbai, India. I have been a facilitator and advisor to the Swedish Industrial 

Design Foundation’s Sommardesignkontoret. In 2009, I was one of only two 

American designers invited to participate in ICSID (International Congress of 

Societies of Industrial Design) Interdesign Citymove, Gellivare, Sweden. In 2016 I 

was a Visiting Professor in the Mechanical Engineering Department at Högskolan i 

Halmstad (Halmstad University) in Halmstad, Sweden.

In 2004, I was included in ID Magazine’s “Design 50.” The editors at ID chose 

to profile the work of 50 US designers in their January/February 2004 Issue - one 

from each state. I was honored as the designer chosen to represent Kansas. ID is the 

largest and most prestigious journal in the US for our profession.

I am a 2015-16 Fulbright Senior Scholar.

I am also a 2019-2020 Global Fulbright Scholar.

I was one of “133 Distinguished Industrial Design Professionals and 

Professors” to sign the Amicus Brief supporting Apple in its case against Samsung 

before the Supreme Court. Other signatories included Dieter Rams, Norman Foster, 

Robert Brunner, Alexander Wang, Paula Scher, Jasper Morrison.

I have offered testimony or prepared expert opinions in at least 25 matters in 

the past five years. A complete listing of cases in which I have offered testimony or 

prepared expert opinions is attached as Exhibit 2 to this report.

Based on these and other experiences, I believe that I am qualified to give 

opinions as an industrial designer skilled in the art with respect to the designs at issue 

here. Due to my work with other industrial designers over the course of my career, I 

also believe I am qualified to give an opinion about what would be understood by 

one skilled in the art of ceiling fans like those at issue here.

I also believe that I am qualified to give opinions about how an ordinary 

observer or consumer would perceive the devices and designs in question. As a 

professional working in the areas of industrial design, I have 46 years of experience 

in industrial design. My job was to design mass-produced products to be attractive, 

useful, and profitable. My ability to understand the product attributes that define a 

successful visual impression with consumers is based on years of user research and 

iterative design of hundreds of products, and continuous collaboration with 

professionals in user experience, marketing, engineering, production, and service. I 

review design resources daily to spot and respond to trends in design, architecture, 

and technology.

DESIGN PRINCIPLES APPLIED

Some of the opinions in this report are based on a working understanding of 

Gestalt principles as they apply to design. As a design educator for 40 years, I can 

confidently say that that the principles of design as originally formulated and taught 

at the Staatliche Bauhaus and based on Gestalt psychology have served as the 

foundation of nearly every formal school of design education in the world. It is 

unlikely that any practicing industrial, graphic, or interior designer would be 

unfamiliar with Gestalt theory as it applies to design.

Gestalt refers to principles of visual perception developed by German 

psychologists in the 1920’s and still used to provide a foundation for design studies 

in universities all over the world. These principles describe how we perceive the 

world around us. Of all the principles, Figure-Ground is the most significant, 

explaining how the eye differentiates an object from its surroundings. The FigureGround principle tells us that in perceiving a visual field, some shapes or contours 

take a prominent role (figure) while others recede into the background (ground).

You can read this page because of the contrast between the black type and the 

white page. We can see different letterforms because we “read” the differences in 

contour or outline of the different characters. We tend to perceive some elements as 

the figure, with a particular shape and contour, while other elements appear as the 

ground, separate from and behind the main focus of the figure. This is usually 

referred to as Figure/ Ground relationship.

Gestalt principles provide background on how the ordinary observer will 

perceive shape and form. Designers regularly rely upon these principals so they 

know in advance how observers will respond to or perceive a design. Seminal texts 

include Joseph Albers’s Interaction of Color, Johannes Itten’s The Elements of 

Color, and Rudolf Arnheim’s Art and Visual Perception: A Psychology of the 

Case: 1:20-cv-04806 Document #: 629-4 Filed: 12/23/22 Page 9 of 106 PageID #:15975 Case: 1:20-cv-04806 Document #: 376 Filed: 08/23/21 Page 8 of 105 PageID #:8433

Creative Eye. These books have been largely superseded by more contemporary 

texts, but the principles of Gestalt continue to provide the basis for most design 

foundation programs.

I specifically selected Gestalt Perception Theory as a scientific framework for 

determining whether or not the design of the Accused Products is equivalent to that 

of the Asserted Patents. Specifically, Gestalt principles are well-understood to be a 

primary scientific theory on which design education and much of modern perception 

science is based. Gestalt theory and related methods for measuring design 

equivalence is considered a primary research reference in the larger field of visual 

perception. Recent peer-reviewed articles support this view1

. 

I have also selected Gestalt Perception Science and related methods because 

Gestalt theory is widely taught at leading industrial design programs, fine art 

programs, and computer vision programs. In fact, I regularly instruct students on 

the use of Gestalt principles in many the industrial design classes that I teach at the 

University of Kansas. Gestalt perception science is the most widely taught general 

theory of shape perception as evidenced by its inclusion in many, if not all, leading 

academic texts. It is my understanding that much of the latest neuroscience related 

to visual perception verifies the basic structure and approach to Gestalt Perception 

Science.

LEGAL PRINCIPLES-DESIGN PATENTS

I have also been informed that the test for determining infringement in design 

patent cases is the “ordinary observer” test. 

The test requires a determination to be made as to whether, in the eye of an 

ordinary observer, giving such attention as a purchaser usually gives and familiar 

with the prior art, two designs are substantially the same in their overall appearance. 

If the resemblance deceives the observer, inducing him or her to purchase one 

supposing it to be the other, the designs are substantially the same. 

THE ORDINARY OBSERVER

In this case, it is my opinion that an ordinary observer would be a customer 

purchasing products I am referring to as “hoverboards”. This purchaser will tend to 

be quite savvy and well-informed. Purchases are often made online. I have 

experience designing bicycles and skateboards sold online, and found that people

typically “do their homework” when buying products such as skateboards and, I 

believe, hoverboards. Hoverboards range in price from $100 to $250 and up, so 

customers research different brands and models online, and often read reviews 

before making a purchase. In my opinion, the ordinary observer will be a wellinformed consumer who is aware of the overall market and the similarities and 

differences of most of the major brands and models.

The most prominent features impacting the overall visual impression to the 

ordinary observer are the design of the two foot pads, the design of the wheels, visual 

details on the “neck between the footpads, and the shape of the fenders that cover 

the wheels, since the user most commonly sees a hoverboard from a position 

standing over the board.

SUMMARY OF OPINIONS

I have evaluated the overall visual appearance of the Patents-in-Suit and the 

design of the Accused Product from the perspective of an ordinary observer 

familiar with the relevant prior art.

It is plainly evident to me that the design of the Accused Product is based on 

the ’857 Patent, which the Defendant is authorized to use, and not based on the 

prior art or the design claims of the Patents-in-Suit.

In my opinion, the visual differences between the claimed designs of the 

Patents-in-Suit and the design of the Accused Product would be obvious to the 

ordinary observer.

MARKMAN CLAIM CONSTRUCTION

In my experience, verbal descriptions of a design are invariably too broad in 

some respects or too narrow in other respects to fully capture an overall claimed 

design. It is my understanding the law recognizes this too. I have been told that the 

Egyptian Goddess case recognizes, (a) “design patents ‘typically are claimed as 

shown in the drawings’”; (b) the trial court is not required to “attempt to provide a 

detailed verbal description of the claimed design”; (c) “a design is better represented 

by an illustration ‘than it could be by any description and a description would 

probably not be intelligible without the illustration’"; (d) but that verbal 

interpretation may be helpful “the claimed design as they relate to the [JM] accused 

design and the prior art”, “the role of broken lines”, “representations...made in the 

course of prosecution history”, and identifying any “purely functional” features. 

While words are capable of generally listing individual features, they are simply 

incapable of communicating the “overall look” of a design patent claim, especially 

Case: 1:20-cv-04806 Document #: 629-4 Filed: 12/23/22 Page 15 of 106 PageID #:15981 Case: 1:20-cv-04806 Document #: 376 Filed: 08/23/21 Page 14 of 105 PageID #:8439

where color is an element of the claim. If a list of elements or features is devised, 

how can we determine a visual or perceptive hierarchy? Depending on the individual 

observer, seeking to devise or deploy such a list, the eye may very well focus on and 

amplify certain aspects of the design and ignore or diminish others as the eye moves 

back and forth between the list and the illustration. There is a reason we use 

photographs on our driver licenses and passports instead of a verbal description.

NON-INFRINGEMENT ANALYSIS OF THE PATENTS-IN-SUIT

I understand that the ordinary observer, when comparing the design of the 

Accused Product and the Patent-in-Suit, must do so with knowledge of the relevant 

prior art. Where the differences between the claimed and accused design are viewed 

in light of the prior art, the attention of the ordinary observer will be drawn to those 

aspects of the claimed design that differ from the prior art. As explained below, it 

is my opinion that the ordinary observer, familiar with the prior art, would find the 

Accused Products’ overall appearance to be substantially different with respect to 

the design claims of the Patents-in-Suit because the overall Gestalt of the Accused 

Product differs in key areas from the body of prior art and the claims of the Patentsin-Suit. 

To be sure, there are important visual features found in virtually all products 

in this category- most products use similar technologies and functional constraints 

of kinematics, ergonomics, performance and environmental considerations. For 

instance, most hoverboards have two wheels (one on either end) that are 6.5”-10” in 

diameter and spaced about 30” apart. There are two platforms to stand on, with a 

narrow pivot in-between, which makes it easier to turn without interference with feet 

or with the ground.

The Gestalt principles of visual perception teaches us that the eye is attracted 

to areas of high contrast. The figure below illustrates some of the Gestalt principles

designers regularly incorporate in their work, and I have relied on in this analysis.

Of all the principles, Figure-Ground is perhaps the most significant, 

explaining how the eye differentiates an object from its surroundings. The FigureGround principle tells us that in perceiving a visual field, some shapes or contours 

take a prominent role (figure) while others recede into the background (ground).

An example of Figure-Ground can be seen when we view the front perspective 

view of the ’723 patent. Our eye is drawn to the footpad areas because the amount 

of detail and the line density makes it the darkest area of the image. The detail and 

density of this area contrasts with the plain surrounding body surfaces creating a 

strong Figure-Ground gestalt.

15

NON-INFRINGEMENT OF THE ’723 PATENT

I have been informed that the test for infringement requires a side-by-side 

comparison of the claims of the patent as represented in the figures (usually drawings 

or photographs) with the Accused Devise (often in photographs). I believe that 

including corresponding figures from the uncontested ’857 patent more clearly 

shows the differences/similarities in the designs. Using well-established Gestalt 

principles, I then compared the differences/similarities between the ’723 Patent and 

the Accused Product through the eyes of “the hypothetical ordinary observer who is 

conversant with the prior art,” as discussed in Egyptian Goddess. 

Through this process, I determined that the overall Gestalt of the Accused 

Product fan is more similar to the design of the ’857 Patent that that of the ‘723 

Patent. The design of the Accused Products differs significantly the design of the 

’723 Patent in several key areas.

There are several key design difference between the design claim of the ’723 

Patent and the Accused Product that would be immediately recognized by the 

ordinary observer. From the Top and Front views, the differences in the shape and 

Case: 1:20-cv-04806 Document #: 629-4 Filed: 12/23/22 Page 18 of 106 PageID #:15984 Case: 1:20-cv-04806 Document #: 376 Filed: 08/23/21 Page 17 of 105 PageID #:8442
16

design of the footpads is clear. Also, an ordinary observer familiar with the prior art 

and other products in the marketplace would recognize that the ’723 claim has 

prominent design element in the middle and the Accused Product is clean, without 

any such design element.

The front view we can see dramatic and obvious difference in the size, shape, 

and character of the lights. In my opinion, this difference would not be unnoticed by 

the ordinary observer.

Although I consider the Top and Front views to be the most important in my 

analysis, simply because these are the views most seen and understood by and 

ordinary observer when comparing the products at the point of sale (online or in 

brick-and-mortar retail environments), the bottom and back views also play a role in 

an ordinary observer’s understanding the overall visual appearance of the designs.

A bottom view reveals substantial design differences. There is a prominent 

central design detail at the center, two strong styling recess areas under the feet, and 

vent hole patterns that are readily noticed because of the Figure-Ground gestalt, as 

well as Closure, Similarity, and Proximity.

Another important design feature that has a significant effect on the overall 

visual impression of the ordinary observer is the size and shape of the fenders. Here

we can see a comparison of the fender design claimed in the ’723 Patent and the 

fender design of the Accused Product. Even to the most casual observer, the 

differences are significant and glaring.

The overall shape of the ‘723 Patent claim is, as I explained earlier, largely 

based on functionality. The dimensions correspond to the dimensions of a human 

foot, the distance between footpads corresponds to approximate “shoulder width” 

dimensions of the user, the narrowing at the center facilitates the needed twisting 

motion without interference with the user or the ground. Prior art listed on the face 

of the patent includes articulating skateboard designs with the narrowing center and 

broadening under the feet, as shown on the US 8,469,376 patent below.

NON-INFRINGEMENT OF THE ‘256 PATENT

There are several key design difference between the design claim of the ’256 

Patent and the Accused Product that would be immediately recognized by the 

ordinary observer. From the Top and Front views, the differences in the shape and 

design of the footpads is clear. Also, an ordinary observer familiar with the prior art 

and other products in the marketplace would recognize that the ’256 claim has 

prominent design element in the middle and the Accused Product is clean, without 

any such design element.

The front view we can see dramatic and obvious difference in the size, shape, 

and character of the lights. In my opinion, this difference would not be unnoticed by 

the ordinary observer.

Although I consider the Top and Front views to be the most important in my 

analysis, simply because these are the views most seen and understood by and 

ordinary observer when comparing the products at the point of sale (online or in 

brick-and-mortar retail environments), the bottom and back views also play a role in 

an ordinary observer’s understanding the overall visual appearance of the designs.

The bottom view reveals substantial design differences. There is a prominent 

central design detail at the center, two strong styling recess areas under the feet, and 

vent hole patterns that are readily noticed because of the Figure-Ground gestalt, as

NON-INFRINGEMENT OF THE ‘195 PATENT

There are several key design difference between the design claim of the ’195

Patent and the Accused Product that would be immediately recognized by the 

ordinary observer. From the Top and Front views, the differences in the shape and

prominent design element in the middle and the Accused Product is clean, without 

any such design element.

The front view we can see dramatic and obvious difference in the size, shape, 

and character of the lights. In my opinion, this difference would not be unnoticed by 

the ordinary observer. The headlight design (which is mirrored on the back as well) 

as depicted in the ’112 Patent is a very prominent design feature substantially 

different from the light design of the Accused Product.

Although I consider the Top and Front views to be the most important in my

CONCLUSION

Based upon my experience as a designer and design educator, my application 

of the Gestalt Principles of Visual Perception, my understanding of the legal 

principles, my analysis of the Patents-in-Suit and the relevant prior art, my review 

of the ’857 Patent, and my review of photographs of the Accused Product, it is my 

opinion that an ordinary observer familiar with the prior art would not find the 

Accused Products to be substantially similar to the claimed designs of the Patentsin Suit.

In my opinion, the visual differences between the claimed design of the ’723 

Patent and the design of the Accused Product would be obvious to the ordinary 

observer. Each element of the ornamental feature, viewed together, only enhances 

the dissimilarity between the Accused Product and the ’723 Patent. The substantially 

dissimilar foot pads, lighting design, the design of the undercarriage and the 

dramatically different fender design creates a substantially different overall visual 

impression to the ordinary observer.

BIOGRAPHY

For nearly 50 years, I have been learning, practicing, and teaching industrial design, often at the

same time. Honored as a Fulbright Senior Scholar in 2015 and again in 2018, I am currently

Professor of Industrial Design at the University of Kansas. I have also taught full-time at Auburn

University and Carrington Technical Institute in Auckland, New Zealand. Additionally, I have

taught short courses at Konstfackskolan in Stockholm and been a visiting professor at Staffordshire

University in Stoke-on-Trent, England, Halmstad University in Sweden, the Royal Melbourne

Institute of Technology in Australia, Kathmandu University in Nepal, and the Indian Institute of

Technology-Bombay in Mumbai, India. My design research has been supported by private and

public grants, and findings presented at national and international design conferences and

institutions. For several years I have been using my experience as both teacher and practitioner of

design to serve as an expert witness in design patent infringement and product liability cases. I was

a signatory to the “133 Distinguished Industrial Design Professionals and Professors” Amicus Brief

supporting Apple in its case against Samsung before the Supreme Court.

Working alone or in collaboration with other professionals, I have designed numerous commercial

products, consumer products, aircraft and boat interiors, graphics, packaging, and exhibits. I was

chosen by the editors at ID Magazine chose as one of the “Design 50”.

Recently, my research efforts have been focused toward using design to create sustainable craftbased enterprises in rural communities in the US, Africa, Nepal, and India.
