Practice Areas

Patent Litigation and Prosecution

Mr. Guo handles patent infringement litigation, patent invalidation petitions before the Patent Reexamination Board, and patent prosecution before the China National Intellectual Property Administration. His technical background in applied physics allows him to understand complex patent claims and technical issues in litigation, and he works effectively with technical experts and patent examiners. He has been involved in several landmark patent cases, including a patent infringement dispute between two Shenzhen technology companies that was selected as a guiding case by the Supreme People's Court, and a patent infringement action brought by Qualcomm against Nokia in China.

In patent prosecution, Mr. Guo prepares and prosecutes patent applications in the mechanical, electrical, and software fields. He advises clients on patentability assessments, drafts patent specifications and claims, and manages the prosecution process through to grant. He also conducts freedom-to-operate analyses and prepares invalidity opinions for clients facing potential infringement claims or seeking to clear competing patents from the market. His prosecution experience includes cases before the CNIPA and his familiarity with Chinese patent examination practice allows him to develop strategies that maximize the scope of granted claims.

Patent Invalidation and Administrative Litigation

Mr. Guo has extensive experience in patent invalidation proceedings before the Patent Reexamination Board and the subsequent administrative litigation before the Beijing IP Court and the Supreme People's Court. He represents both patentees defending their patents against invalidation challenges and petitioners seeking to clear patents that block their freedom to operate. His combined technical and legal background is particularly valuable in invalidation proceedings, where understanding the prior art and the patent's technical contribution is essential to developing an effective case.

Trademark Services

Mr. Guo advises clients on trademark registration, portfolio management, and enforcement in China. His services cover trademark search and clearance, domestic and international registration, trademark review, opposition, invalidation and cancellation proceedings, trademark monitoring and portfolio management, and trademark infringement litigation. He also handles administrative enforcement actions and customs protection for trademark rights.

Copyright Services

Mr. Guo handles copyright registration for literary, artistic, and software works, copyright licensing and transfer agreements, and copyright infringement litigation. He advises clients on the protection of software copyrights, which is particularly relevant given China's growing software industry and the prevalence of software piracy.

Unfair Competition and Trade Secrets

Mr. Guo advises clients on trade secret protection, including the establishment of trade secret protection systems within client organizations, risk assessment for trade secret misappropriation, and litigation arising from trade secret theft or misuse. He also handles cases involving passing off, commercial defamation, and false advertising under China's Anti-Unfair Competition Law.

Comprehensive IP Services

Mr. Guo provides a full range of IP services beyond litigation and prosecution, including IP portfolio management and strategy, IP compliance and audit, IP due diligence for M&A and investment transactions, IP licensing and commercialization, and technology import and export legal advisory. He also advises companies preparing for IPOs on their IP-related disclosures and risk management. Several cases handled by Mr. Guo have been selected for inclusion in the Supreme People's Procuratorate guiding cases series and the Beijing courts' top ten IP protection cases, reflecting the significance and quality of his work in the IP field.
