IP Management & Strategic Advisory
Domestic and overseas filing for patents and utility models, trademarks and service marks, and industrial designs.
Beyond protecting and managing copyrights, computer programs, and trade secrets, we provide systematic management of a company's IP portfolio—patents, trademarks, and designs—including rights maintenance, renewals and annuity handling, the establishment of employee-invention compensation schemes and trade-secret policies, advisory on internal security to prevent leakage of core technology, and review of licensing status and renewal strategy, so that intellectual property can be leveraged as a genuine corporate asset.
Injunctions and damages litigation for infringement, preliminary injunctions, invalidation and scope-confirmation trials before the IP Trial and Appeal Board, decision-cancellation suits at the Patent Court and Supreme Court, pre-assessment and expert opinions on infringement, drafting of warning and response letters, and invalidity reviews.
Infringement and invalidation trials/litigation for patents (and utility models), trademarks, designs, and copyrights; litigation over trade-secret infringement and unfair competition; mediation and arbitration of IP disputes; and support for overseas IP litigation and mediation.
In addition to patent and trademark searches, overseas patent searches, patent information analysis (PM), patent product investigations, and patent document translation, we assess registrability through pre-filing prior-art reviews, analyze competitors' patent trends and broader technology trends, support R&D direction-setting through patent maps, review infringement and design-around strategies, conduct invalidity searches, and prepare patent-valuation materials for technology transfer and transactions—delivering search and analysis that underpin data-driven strategic decisions.
Patent licensing, IP transfer and other transaction agreements, IP due diligence, technology-based joint-venture (JV) formation, IP transaction brokerage, and IP financing.
