Areas of Practice
With deep expertise in intellectual property law and a USPTO registration, the Law Office of Charles C. Liu provides comprehensive legal protection for your innovations, brands, and creative works.
Utility Patents
Utility patents protect the functional aspects of your invention. We guide you through the entire prosecution process — from prior art searches and claim drafting to USPTO examination and final issuance.
Provisional Patents
A provisional patent application secures your priority date and gives you 12 months to refine your invention before filing a full utility patent. We help you file strategically to maximize protection.
Trademarks
Your brand is your identity. We assist with trademark clearance searches, USPTO registration, office action responses, and enforcement strategies to protect your marks in the marketplace.
International Protection
Innovation knows no borders. We coordinate PCT international patent applications and foreign filing strategies, helping you secure protection in key markets around the world.
Copyright Law
Copyright protects your original creative works — from software and written content to artistic creations. We handle registration, licensing agreements, and infringement matters.
IP Strategy & Counseling
Beyond filings, we provide comprehensive IP portfolio management and strategic counseling to align your intellectual property assets with your business goals and competitive landscape.
