版权方 (bǎnquánfāng): copyright holder

方 (fāng, 'side / party') is a productive noun-suffix in legal/business Chinese: 甲方 / 乙方 (jiǎfāng / yǐfāng, Party A / Party B), 厂商方 (chǎngshāngfāng, manufacturer), 平台方 (píngtáifāng, platform side), 用户方 (user side). 版权方 names the side that owns the copyright.

Chinese platforms aggressively pre-emptive about 版权方 takedowns since the late 2010s 影视版权 (TV/film copyright) wars between iQiyi, Tencent Video, and Youku. The phrase '应版权方要求' ('at the copyright holder's request') is the canonical reason given when a video disappears.
