4. LEGAL BASIS FOR CLAIMS

A. Federal Claims

Lanham Act Trademark Infringement (15 U.S.C. § 1114): Unauthorized use of a confusingly similar mark. The Third Circuit applies the Interpace Corp. v. Lapp, Inc., 721 F.2d 460 (3d Cir. 1983) factors for likelihood of confusion analysis, including: (1) degree of similarity; (2) strength of plaintiff's mark; (3) price of goods; (4) channels of trade; (5) advertising; (6) intent of defendant; (7) actual confusion; (8) quality of defendant's goods; (9) sophistication of consumers; and (10) other relevant factors.

False Designation of Origin (15 U.S.C. § 1125(a)): Infringer's use creates a false impression of source, sponsorship, or affiliation.

Trademark Dilution (15 U.S.C. § 1125(c)): Dilution by blurring or tarnishment of famous marks.

Copyright Infringement (17 U.S.C. § 501): Unauthorized reproduction, distribution, display, or derivative works of copyrighted material.

Patent Infringement (35 U.S.C. § 271): Unauthorized making, using, selling, or importing of patented products/processes. The U.S. District Court for the District of Delaware handles a significant portion of the nation's patent litigation and has developed specialized local patent rules (D. Del. LPR).
