Representative Matters

  • [2025] | Patent mining and portfolio layout in new energy: For a key project of a new energy company, Guo built a tiered portfolio strategy around product protection: core patents on the central technology, surrounding patents on derivative structures, preparation methods, alternatives, application scenarios and tooling. She ran a freedom-to-operate (FTO) screening in parallel, identified patent risks and produced design-around recommendations.
  • [2025] | Patent landscape analysis in new energy: Guo carried out competitor patent landscape analysis for a new energy company, mapping the competitor’s technical development path and portfolio barriers and identifying high-risk patents and white space, as intelligence for R&D design-around, patent mining and FTO screening.
  • [2025] | PCT international filings in new energy: Guo managed PCT filings for a new energy company’s key export product line, coordinating drafting, translation, international search and responses, so as to secure priority for core technologies and support selective national filings in target overseas markets.
  • [2019] | Patent quality control in new energy: Guo established a full-lifecycle quality control mechanism, moving risk assessment to an earlier stage and tightening review of invention disclosures, claim structure and application texts in order to define the scope of protection precisely and improve patent stability.
  • [2022] | Patent invalidation in mechanical engineering: Guo conducted in-depth invalidation analysis of patents in dispute and at risk, searched the prior art comprehensively, identified defects in the claims, assessed stability and the prospects of invalidation, and produced an invalidation strategy supporting non-infringement defenses and risk mitigation.
