Six core practices.
One discipline.
From establishing a right to defending it in court...
One firm,
six mutually-engaged practices.
Our practice covers the full arc of an intellectual-property right: rights established and defended on the administrative front; rights enforced through litigation; rights monetized through licensing and transactions; rights protected through investigation, monitoring, and risk-control architecture — held together by ongoing strategic counsel.
“Rights establishment” is the spine of the practice. It’s where Kangrui’s reputation was built, and the discipline that quietly determines outcomes in every other area downstream.
Defending the
edge of every right.
Trademark opposition / invalidation / refusal review / non-use cancellation · Patent invalidation · Copyright registration disputes · Administrative litigation
Whether a right will hold in the next infringement battle is decided long before that battle begins — in the invalidation chamber, the refusal-review docket, the administrative-litigation panel. Confirmation work is where Kangrui was built. We act before the CNIPA, the Trademark Office, and the Beijing IP Court — securing high success rates on the procedures that quietly determine every downstream outcome.
Well-known trademark recognition + invalidation — BVLGARI / DEMAE ICCHO
Through targeted evidence of pre-application fame and a documented pattern of bad-faith filings, we secured well-known mark recognition and invalidation of the disputed registrations — landmark outcomes for both clients.
Winning in court through
rigor, not volume.
Patent · trademark · copyright · trade-secret infringement litigation · Anti-unfair competition · Domain & company-name disputes
Our litigators have represented clients in complex, high-stakes infringement and unfair-competition matters before the Supreme People's Court, the Beijing IP Court, and specialized IP tribunals across the country — including SWAROVSKI, Lotus, Bureau Veritas, ORBOTECH, and Bugaboo. The cases that win, we find, are won not through escalation but through precise command of fact, rule, and tempo.
Well-known status + cross-border infringement — SWAROVSKI · Lotus
In SWAROVSKI we systematically established well-known status and the defendant's intentional imitation across both branding and corporate naming — securing damages of RMB 210,000. In the Lotus packaging case, we coordinated historical fame evidence with embassy support and a parallel design-patent invalidation, securing RMB 400,000 in damages.
Turning blurred facts
into admissible evidence.
Background investigation · Infringement investigation · Online investigation
Investigative capabilities are a hallmark of Kangrui. From corporate background investigations and trademark usage investigations to various types of infringement investigations, developing evidence-gathering strategies, and collecting and securing evidence of infringement and compensation, we leverage our years of accumulated investigative methodologies to forge fragmented clues into a complete and legal chain of evidence.
Six-month infiltration investigation — Bugaboo criminal case
A half-year investigation uncovered the target's sales channel, manufacturing site, and two principal individuals. We orchestrated a controlled on-site transaction and assembly to secure irrefutable evidence of trademark "use" — enabling arrest, conviction, and a suspended three-year sentence in the regional manufacturing hub.
Combining litigation and non-litigation methods, we can comprehensively combat infringement.
Administrative complaints · Customs protection · Exhibition monitoring · Criminal enforcement coordination · Compliance audits
By monitoring to promptly detect infringements, by administrative investigations and criminal protection to quickly combat infringements, and by customs border interception to ensure that infringing products do not flow overseas, intellectual property rights can be protected through multiple means.
AMR enforcement bridged into civil litigation — ORBOTECH
Leveraged a favorable AMR ruling as anchoring evidence in subsequent civil litigation; the strategic bridging of administrative enforcement and judicial action secured RMB 480,000 in compensation — maximizing the value of the rights-protection effort.
Turning rights
into commercial value.
Negotiation · Assignment · Licensing · Recordation & filing · Contract drafting & review · IP due diligence
Intellectual property creates real value only when put to work. Through licensing, assignments, joint development, and IP-backed financing, Kangrui structures the agreements, conducts the diligence, and drafts the documents that turn intangible assets into tradable, financeable, scalable competitive advantage.
Higher-altitude judgment
before every key decision.
Legal advisory · Search & analysis · IP strategy · Cross-border disputes · Corporate & employment law · Standing counsel
As long-term strategic counsel, Kangrui partners with management, R&D, brand, and commercial teams — bringing forward-looking judgment to product launches, cross-border disputes, organizational change, and IP portfolio strategy. We translate dense legal reasoning into the judgment tools the business actually needs.
