先ごろ、国際的に権威のある知的財産関連メディアの「知的財産管理（Intellectual Asset Management，IAM）」が「2021 IAM Patent 1000」ランキングを発表し、集佳は長年にわたる卓越したサービスおよび顧客から広く認められたことにより、専利出願および専利訴訟の二大分野の年間推奨事務所に再度入選した。また、集佳パートナーの李徳山博士と潘煒博士が専利出願分野における信頼される専門家として、傑出人物ランキングに再度入選した。

　　当該ランキングでは集佳の長年にわたる専門業務の蓄積と開拓精神が認められ、調査を受けた顧客の評価が直接引用され、集佳の専利に関する法律サービスが高く評価された。 “More than 200 patent attorneys join forces to make Unitalen one of the single biggest sources of Chinese patent applications. The firm churns out grants in every significant technical area, with part of its secret being a network of branches that are able to service local clients from all over the country. “Their processes are finely tuned and always timely, with communication that is second-to-none.” One local practitioner observes that Unitalen has “expanded greatly in China and also become very much an international firm.” A well-populated legal department enables the group to handle dozens of civil litigation cases simultaneously, on top of its heavy administrative docket. Vice president Deshan Li is a superb advisor on patent strategy in the round and a thought leader respected throughout the industry. Wei Pan adroitly handles both incoming and outgoing work related to Europe: automobiles, aircraft, appliances and other mechanical apparatuses are his bread and butter.”
