The Eye as Legal Judge: Design Patent Uncertainty and ISO 56001 Implications for Taiwan Firms

Winners Consulting Services Co., Ltd. reminds executives in Taiwan that the protective boundary of a design patent is never a clear line but rather an image where "the eye alone is the judge." Rebecca Tushnet's 2012 academic research, published on arXiv, points out that design patent infringement adjudication relies heavily on visual comparison, making the current testing standard inherently uncertain. If companies fail to incorporate design patents into the systematic protection framework of an ISO 56001 Innovation Management System (IMS), they will face evidentiary challenges and the risk of high damages in infringement litigation.

About the Author and This Study

Rebecca Tushnet is a professor at Harvard Law School and a leading scholar in intellectual property law, with significant academic influence, particularly on the intersection of copyright, trademark law, and design patents. She is also a renowned commentator on the U.S. Copyright Act and the Lanham Act. Her research is unique in its approach of challenging the assumptions of mainstream legal frameworks from a "legal outsider" perspective, revealing their internal contradictions.

This paper was published on arXiv in 2012 as an academic preprint. However, because its subject matter addresses a critical pain point in intellectual property law practice, it has been frequently cited and discussed in the design patent academic community. The paper is concise yet sharp in its analysis, making it particularly suitable for legal and business management professionals who need to quickly grasp the logic of design patent infringement adjudication.

Design Patent Infringement: Why Is the "Eye" the Only Judge?

Tushnet's core argument is that design patents are the only protective tool in the entire intellectual property system that is centered entirely on "visual images," yet the legal system's ability to handle images remains severely inadequate.

Key Finding 1: The Structural Instability of Design Patent Infringement Test Standards

U.S. courts primarily use the "ordinary observer test" to determine design patent infringement: an "ordinary observer familiar with the prior art" judges whether two designs are similar enough to be confused. Tushnet points out a fundamental logical contradiction in this standard—it requires judges and juries to use "visual perception" as a legal judgment tool, but legal training never teaches how to systematically compare images. This leads to outcomes in design patent infringement litigation that often depend on the decision-maker's visual intuition rather than a consistent legal standard. Taiwan's Intellectual Property and Commercial Court faces similar practical challenges with inconsistent standards for judging design similarity, resulting in widely varying damage awards (such as the NT$5 million judgment mentioned at the beginning of this article).

Key Finding 2: Copyright Law's Handling of Images Offers a Model for Design Patents

Tushnet further compares the different ways design patent and copyright law handle images. While copyright law also deals with visual similarity, it has developed a more nuanced analytical framework for determining "substantial similarity," such as distinguishing between "conceptual separability" and "physical separability," and the boundary between "protectable expression" and an "unprotectable idea." She argues that if design patent law could adopt some of copyright law's analytical tools, it would help improve the predictability of infringement judgments. However, she also acknowledges that this path is not easy, as the subject matter of design patents (purely visual appearance) and copyright (expression) are fundamentally different.

Key Finding 3: The Limitations of Sui Generis Protections

Tushnet warns that design patents exist in a "visual silo" within the intellectual property system. Their integration with other protection mechanisms like copyright, utility patents, trademarks, and GDPR Data IP still lacks a systematic design. For businesses, this means that relying solely on design patents is insufficient to build a comprehensive protective network for brand visual assets.

Three Key Takeaways for Taiwanese Enterprises on Trade Secret Protection and Innovation Management (IMS)

Although Tushnet's research focuses on U.S. design patent law, her core insight into the "uncertainty of images as legal tools" has direct practical implications for Taiwanese companies implementing the ISO 56001 Innovation Management System (IMS).

First, systematic preservation of design documents is a fundamental task of IMS. ISO 56001 requires companies to establish a Knowledge Management mechanism to ensure the recording, storage, and protection of innovation knowledge. For design patents, this means creating a complete "design evolution record"—from conceptual sketches and version iterations to the final design, each stage should have a timestamp and version control. In infringement litigation, this record becomes crucial evidence for proving the originality and timeline of the design's creation.

Second, the "reasonable confidentiality measures" requirement of Taiwan's Trade Secrets Act is directly relevant to design protection. According to Article 2 of Taiwan's Trade Secrets Act, a trade secret must meet three criteria: secrecy, economic value, and the owner having taken "reasonable measures to maintain its secrecy." If design drafts and visual prototypes are not included in a company's confidentiality management system, any leak not only forfeits the novelty required for a design patent application (due to public disclosure) but also prevents the company from seeking protection under the Trade Secrets Act.

Third, the value of design patents and trade secret protection for R&D innovation are complementary and should be integrated within the IMS framework. Once a design patent is filed, it must be publicly disclosed, and its protection term is 12 years (Article 135 of Taiwan's Patent Act). In contrast, undisclosed technical know-how and user research data from the design development process can be protected indefinitely under the Trade Secrets Act. Companies should develop a "design asset classification inventory" within their IMS framework to clearly distinguish which design outcomes are suitable for patenting and which should be kept as trade secrets.

How Winners Consulting Services Helps Taiwanese Enterprises Build Design Asset Protection Mechanisms

Winners Consulting Services Co., Ltd. assists Taiwanese companies in implementing the ISO 56001 international standard for innovation management and establishing protection mechanisms compliant with Taiwan's Trade Secrets Act to prevent the leakage of R&D results. Regarding design patent protection, we offer the following three concrete action recommendations, implemented over a systematic 7 to 12-month timeline:

1. Months 1-3: Design Asset Assessment and Classification — Consultants from Winners Consulting Services will help the company create a "design asset inventory." In line with ISO 56001 knowledge management requirements, we will systematically assess existing design outcomes, classifying them into three categories: "suitable for design patent application," "suitable for trade secret protection," and "in the public domain." We will also evaluate whether current confidentiality measures meet the "reasonable measures" requirement of Article 2 of Taiwan's Trade Secrets Act.
2. Months 4-8: Establishing IMS Control Points in the Design Development Process — We will embed IMS control mechanisms into the company's existing design development workflow. This includes a design version control system, confidentiality classification management for design drafts, and standardized Non-Disclosure Agreement (NDA) templates for collaborations with external design firms. This ensures that every stage of design creation has a complete timestamped record, preparing evidence in advance for potential future infringement litigation.
3. Months 9-12: Integrated Planning of Design Patent Application Strategy and Trade Secret Protection — We will assist the company in developing a "design IP portfolio strategy," clearly defining which design outcomes should be patented and when, and which should be maintained as long-term trade secrets. We will also establish a regular review mechanism to ensure that the protection strategy for design assets can be dynamically adjusted with market competition, in line with the Continual Improvement requirement of ISO 56001.

Frequently Asked Questions

What are the practical implications of the "ordinary observer test" for design patent infringement for Taiwanese companies?

Taiwan's Patent Act uses an "ordinary consumer" perspective, which is logically similar to the U.S. "ordinary observer test" analyzed in Tushnet's paper, both relying heavily on subjective visual comparisons. This means that if Taiwanese companies fail to maintain a complete design evolution record from the early stages of development, they will struggle to effectively prove the design's originality and timeline in an infringement lawsuit. According to the practices of Taiwan's Intellectual Property and Commercial Court, damage awards for design patent infringement range from hundreds of thousands to millions of New Taiwan Dollars, and the outcomes are highly uncertain due to inconsistent standards for determining design similarity. Companies should systematically establish a design document management system under the ISO 56001 IMS framework to mitigate litigation risks.

When protecting design outcomes, how should Taiwanese companies choose between design patents and trade secrets?

The two are not mutually exclusive but complementary. A design patent is suitable for protecting a finalized visual appearance with market competitiveness, offering a 12-year protection term under Article 135 of Taiwan's Patent Act, but it requires public disclosure upon application. A trade secret is ideal for protecting undisclosed drafts, user research insights, and design know-how during the development process. It can be protected indefinitely under Taiwan's Trade Secrets Act, provided it meets the three criteria in Article 2: secrecy, economic value, and reasonable confidentiality measures. It is recommended that companies establish a "design asset classification inventory" within their ISO 56001 IMS framework to dynamically adjust their use of these two protection mechanisms at different stages of the product lifecycle.

How does ISO 56001 help companies systematically manage design patent assets?

ISO 56001's Innovation Management System (IMS), specifically Clause 7.1.6 on "Knowledge," requires organizations to identify, acquire, store, and protect the knowledge needed for innovation. For design patents, this requirement translates into three concrete actions: first, establishing a design version control system to ensure every design draft is timestamped; second, creating a confidentiality classification standard for design assets that complies with the "reasonable confidentiality measures" of Taiwan's Trade Secrets Act; and third, setting up a regular review mechanism to assess the protection status of existing design assets. A typical implementation timeline for ISO 56001 is 7 to 12 months, divided into three phases: current state diagnosis (months 1-3), system design and implementation (months 4-9), and validation and optimization (months 10-12).

How can the costs and expected ROI of implementing an ISO 56001 design asset management system be evaluated?

The implementation cost for an ISO 56001 design asset management system in a mid-sized manufacturing company typically ranges from NT$500,000 to NT$1,500,000, covering consulting, system setup, and training. In terms of expected benefits, based on our firm's practical experience, a systematic design asset management system can reduce design infringement risk exposure by approximately 30% to 50%. In the event of litigation, it significantly improves the efficiency of evidence gathering, shortening the litigation cycle. In the long term, a comprehensive design asset inventory also helps companies accurately represent the market value of their design assets in licensing negotiations, financing evaluations, and M&A, thereby increasing the company's overall valuation.
