Partner One Acquisitions Inc. and Assima USA LLC v. Whatfix Private Limited, Whatfix, Inc.

Partner One · United States District Court for the District of Delaware · January 27, 2026 · No. No. 25-209

Summary

The United States District Court for the District of Delaware addresses Whatfix's motion to dismiss a patent infringement action involving U.S. Patent Nos. 8,087,007 and 9,285,948. The court holds that claim 1 of the '007 patent is directed to patent-ineligible subject matter under 35 U.S.C. § 101, while claim 1 of the '948 patent survives the eligibility challenge, and concludes that the plaintiffs plausibly alleged willful infringement.

Holdings

  1. Claim 1 of the 007 patent is patent-ineligible because it is directed to the abstract idea of enabling a user to directly modify graphical user interfaces in a simulation file without affecting the underlying software and lacks an inventive concept.
  2. Claim 1 of the 948 patent is patent-eligible because it is directed to a specific technological solution using hierarchically linked screen templates to permit modification of a common interface element across multiple display screens, rather than to the abstract organization or presentation of information.
  3. Assima plausibly pleaded willful infringement because its pre-suit notice letter identified the asserted patents, identified Whatfix's allegedly infringing Mirror product, and asserted that the product infringed those patents.
  4. The complaint asserted infringement of claims beyond claim 1 of the 007 patent; therefore, dismissal of claim 1 did not require dismissal of the 007 patent or its remaining claims.
  5. Assima was granted leave to amend.

Questions Presented

  1. Whether claim 1 of U.S. Patent No. 8,087,007 is directed to an abstract idea and lacks an inventive concept under the Alice patent-eligibility framework.
  2. Whether claim 1 of U.S. Patent No. 9,285,948 is directed to an abstract idea under 35 U.S.C. § 101.
  3. Whether Assima plausibly pleaded willful infringement based on its complaint and pre-suit notice letter.
  4. Whether the complaint asserted infringement of claims beyond claim 1 of the 007 patent.
  5. Whether Assima should be granted leave to amend.
