Rasmussen Instruments, LLC v. Depuy Synthes Products, Inc., No. 23-1855 (October 6, 2025) (nonprecedential); Patent Nos. 9,492,180; 10,517,583

Key points:

• A plaintiff must own the asserted patent at the time suit is filed to have standing.
• A present-tense assignment (“hereby assigns”) immediately conveys ownership and cannot later be undone without a formal reassignment.

St Case1tech, LLC v. Squires, No. 23-2305 (October 9, 2025) (nonprecedential); Patent Nos. 8,111,839; 9,124,982

Key points:

• A party forfeits a claim-construction argument on appeal if it presents a new or broader construction than the one raised before the PTAB.
• The intrinsic record controls claim meaning where the specification clearly defines the scope of the disputed term.

St Case1tech, LLC v. Squires, No. 23-2294 (October 9, 2025) (nonprecedential); Patent Nos. 8,111,839; 9,124,982

Key points:

• The Federal Circuit applied the same reasoning from its companion decision involving the related ’839 patent, affirming that the challenged claims were unpatentable for obviousness.
• Where two patents share a common specification and identical claim issues, the Federal Circuit may affirm by direct reference to its companion decision.

St Case1tech, LLC v. Squires, No. 23-2335 (October 9, 2025) (nonprecedential); Patent Nos. 9,609,424

Key points:

• A claim term is interpreted according to its plain language and the specification, and limitations from embodiments or figures cannot be imported into the claim.
• A processor limitation that recites evaluation of a parameter does not require that the processor also perform unrelated signal generation or excitation functions unless expressly stated.
