Home/Legal partner for innovative companies

What we do

Four capabilities that most of our instructions fall into. Where a matter spans several of them, one team runs it end to end rather than handing it between departments.

Intellectual Property & Technology

Patent prosecution and invalidation, freedom-to-operate analysis, trade secret protection, trademark and copyright portfolios, technology transfer and IP due diligence.

Commercial Dispute Resolution

Sale of goods, technology development and service contracts, equity and shareholder disputes, arbitration and enforcement, including remedies when enforcement reaches a dead end.

Corporate Legal Counsel & Compliance

Day-to-day counsel for technology companies, equity and financing documents, labour and employment, data and personal information compliance, and criminal compliance for companies.

Why Shou Jin

Dual qualification

We hold both the lawyer practising certificate and the patent attorney qualification, so technical facts can be assessed by the same team that argues the case.

Science backgrounds

Around 80% of our lawyers have a science or engineering degree, which matters when a dispute turns on claim construction or test data.

Integrated teams

Matters crossing several legal relationships are staffed as one team with a single lead lawyer and one point of contact.

Three offices

Beijing head office with coordinated coverage in Hangzhou and Guangzhou for matters that need to be handled on the ground.
