Los Angeles Intellectual Property Litigation Lawyers 

In a global economy, these disputes frequently cross borders. Manufacturing, distribution, and development may take place in different countries, increasing complexity and risk. 

Our firm’s long-standing international connections enable us to coordinate with qualified intellectual property counsel worldwide when foreign proceedings or cross-border enforcement are necessary.

Proven Litigation Experience

Our litigation record reflects careful preparation and decisive advocacy. Attorney Marc E. Hankin’s wins include: 

• Successfully defending a patent infringement claim by one computer mouse manufacturer against another computer mouse manufacturer and winning a summary judgment of non-infringement.
• Defending a foreign manufacturer wrongly accused of infringing a U.S. manufacturer’s patent, trademark, and copyright. After proving at the depositions that the plaintiff did not have the rights it claimed and that the defendant did nothing wrong, our firm negotiated a quick settlement, and the plaintiff also paid the defendant $50,000 toward attorneys’ fees.

These outcomes underscore our firm’s approach: identify weaknesses early, apply pressure strategically, and position cases for favorable resolution rather than unnecessary prolongation.

Industry-Focused Litigation Insight

Fashion & Creative Industries

Los Angeles is home to the nation’s largest garment district, and local, state, and federal courts have substantial experience with intellectual property disputes involving fashion, design, and creative works. 

We represent companies and designers seeking to protect logos, patterns, fabrics, accessories, and functional design elements such as closures and hardware.

Our firm also advises on clearance strategies, “freedom to use” opinions, and licensing agreements that allow creative work to be monetized while reducing litigation risk. When disputes arise, we litigate to protect both creative expression and commercial advantage.

Technology & Manufacturing

HPL works extensively with manufacturers and technology companies producing:

• Software
• Hardware
• Medical and dental devices
• Home electronics
• Green technology
• Consumer products.

We litigate patent, trademark, and copyright disputes in U.S. federal courts and advise clients on protecting confidential processes through trade secret law when patent protection is not pursued.

Trade secret disputes often involve former employees or partners. Our team helps clients establish safeguards, contractual protections, and enforcement strategies to protect proprietary information before and after conflicts arise.

Protecting Intellectual Property Locally & Globally

Because modern business is global, intellectual property disputes often extend beyond U.S. borders. HPL maintains a cooperative network of intellectual property attorneys across major manufacturing and technology markets, including Asia and Europe. This global perspective supports coordinated strategies when intellectual property rights are challenged internationally.
