The U.S. Court of Appeals for the Federal Circuit’s recent decision in Range of Motion Products v. Armaid is another reminder that, if care is not taken, design patent scope can be narrowed significantly in the U.S. through functionality analysis—often at the claim construction stage—and even result in summary judgment of non-infringement.

For many product-focused companies, design often is the product. Differentiation lives in surface ornamentation, overall look-and-feel, and visual details that drive purchasing decisions often long before utility is evaluated. Against that backdrop, many brands are reexamining copyright law as a faster, more flexible tool for protecting product aesthetics.

As we wrote about recently here, Examiners continue to rely on the USPTO’s current guidance on the definiteness standard set forth by the Court of Appeals for the Federal Circuit (“Federal Circuit”) in In re Maatita, 900 F.3d 1369, 1377 (Fed. Cir. 2018), that ignores the Federal Circuit’s broader instruction—reasonable certainty is all that is required to satisfy the requirements of 35 U.S.C. § 112, not the specific type or quantities of views that the Applicant has chosen to use.

On August 8, 2025, Baylor University filed a federal lawsuit against Boston University alleging trademark infringement and unfair competition over Boston University’s use of an interlocking BU design.

The U.S. Patent and Trademark Office (USPTO) has announced the rollout of DesignVision, an advanced AI‑powered image search tool now integrated into the examination system for U.S. design patent applications. According to the Official Gazette notice published July 16, 2025, DesignVision enables examiners to perform federated searches of U.S. and foreign industrial design and trademark databases—spanning over 80 registers—using only image inputs. Results are ranked by visual similarity, allowing faster and more precise prior art discovery. The notice clarifies that this tool is intended to augment existing textual search methods, not replace them.

Expedited Patent Issuance
Starting May 13, 2025, the USPTO has begun accelerating the issuance of patents after the issue fee has been paid. Specifically, the duration between the Issue Notification and the Issue Date will be reduced to approximately two weeks instead of the current three-week time period. The USPTO has noted that it has been able to implement this improvement in view of its technology modernization efforts. More information on this update can be found at the USPTO’s website here.

In 2024, design patent law encountered a couple of major changes: the implementation of a new design patent bar, and the upending of decades of obviousness law under 35 U.S.C. § 103 in view of the en banc United States Court of Appeals for the Federal Circuit (CAFC)’s decision in LKQ Corporation v. GM Global Technology Operations LLC, which we discussed here. Looking back at last year’s design patent issuance statistics, we now take the time to determine whether, if at all, the issuance numbers of U.S. design patents were impacted by these changes.

“Aber ist es Kunst?”
That question—“But is it art?”—was before the German Bundesgerichtshof (“BGH”), or Federal Court of Justice, in a recent proceeding involving the well-known Birkenstock sandal design. Birkenstock Group (“Birkenstock”) had sought relief against three rival sandal makers, asserting that the defendants’ products infringed Birkenstock’s copyright on its sandal design. Exemplary designs at issue are shown below.

Design patents in the U.S. typically include two types of shading. The first and most common type of shading used in U.S. design patents is opaque shading, which illustrates a non-transparent or non-translucent surface of an article of manufacture. The second type of shading used in U.S. design patents is oblique shading, which illustrates a transparent or translucent surface of an article of manufacture. Specifically, MPEP § 1503.02(II) states that “[o]blique line shading must be used to show transparent, translucent and highly polished or reflective surfaces, such as a mirror.” Therefore, if the article of manufacture is intended to have some level of transparency or translucency, the USPTO requires that oblique shading be used.
