Faculty

Both nationally and internationally, Mr. Katz is considered one of the premier practitioners in the field of industrial designs, leading the way in the procurement and enforcement of design patents. On behalf of the firm’s clients, he has helped procure more than 10,000 design patents in the U.S. and more than 30,000 design patents/registrations outside the U.S. and has helped to successfully enforce over 100 design patents. Leaders from foreign design patent offices have consulted with him regarding industrial design policies, and he has served as an expert in design patent litigations. Mr. Katz holds leadership positions in several professional organizations, including ABA, AIPLA, FICPI and INTA. He is the past Chair of INTA’s Designs Committee and Vice President of FICPI’s U.S. Section. For the ABA Section of Intellectual Property Law, he currently serves as Liaison to FICPI.

Mr. Katz is a former Chair of the Industrial Design Section for both FICPI and AIPLA, and also a member of IDSA and IPO.

Mr. Carani is nationally recognized in the field of design law, regarding the protection and enforcement of aesthetic design through the use of design patents, copyrights and trade dress. A registered attorney before the USPTO, Mr. Carani secures and enforces design rights for some of the world’s most design-centric companies and designers. He has litigated design right cases in subject matter areas ranging from footwear and apparel to medical devices and furniture. In 2016, IAM Magazine included Mr. Carani in its IAM 1000 referring to him as one of the U.S.’s “pre-eminent design law experts.” He is currently the Chair of the AIPPI Design Rights Committee and former Chair of both the ABA’s Design Rights Committee and AIPLA Committee on Industrial Designs.

In his representation of plaintiffs, his successes include a judgment in excess of $500 million. As counsel for defendants, he has achieved complete defense victories through summary judgment and at trial. Mr. Sabri represents clients in the technology, life sciences, and consumer products industries. He has advised on and litigated matters involving blockchain, touch technology software and hardware, network security, semiconductors, surgical robotics, antibody development, and noninvasive prenatal diagnostics.
Description
By definition, design patents protect ornamental designs. The standard remains unsettled for determining whether a design or design feature is merely decorative--and the impact of that determination. Unlike utility patents, design patent applications are not published when the applicant files directly with the USPTO.
Further, the application's prosecution history is not publicly available until the application issues unless it is a divisional or continuation application. Consequently, less information is available about design patent applications until the issue of the application.
Counsel must find the proper balance when claiming designs. Applicants will often use portion-claiming techniques, which help protect the innovative portions of a design while making it more difficult to "design around" the patent. However, it may also make it harder to get the patent because it is more susceptible to the prior art.
Counsel should consider filing applications with multiple embodiments or filing multiple applications for a design concept with different degrees of scope.
Listen as our authoritative panel of patent attorneys examines critical considerations when defining and drafting design patent claims and discusses how the courts treat claim construction issues for design patents.
