Plaintiff-side IP enforcement for businesses whose brands, products, and creative work are copied online.
Sophie works with brand owners, creators, and product companies facing counterfeit and copycat sales on online marketplaces, trademark and copyright disputes, and cross-border enforcement questions involving overseas sellers. Her technical background in software engineering informs her work on the evidence and platform mechanics that drive online IP disputes.
JiangIP represents rights holders. This page does not concern defense of accused infringers. Services are available in English and Mandarin Chinese (中文服务可用).
Evidence first. Then the proportionate response.
Define the problem.
Identify the rights involved, the recurring sellers, the platforms, and the business harm an enforcement plan must address.
Develop usable evidence.
Plan screenshots, test purchases, seller attribution, and documentation appropriate to the matter.
Choose the response.
Evaluate platform complaints, demand letters, negotiated resolutions, and litigation by cost, urgency, and likely impact.
Every matter is different. Available claims, remedies, timing, and cost depend on the facts, the rights at issue, the other parties, and the forum.
What to send for the initial conflict check.
Sophie lives in Chicago with her family and their dog. She reads biographies, history, and science fiction, and crochets — a deliberate counterbalance to the pace of litigation.
