[Cryptocurrency organization COPA launches action to stop blockchain "patent giants"] Golden Finance reported that the crypto advocacy organization "Cryptocurrency Open Patent Alliance" (COPA) and the patent-focused organization "Unified Patents" have launched a campaign against blockchain and crypto technology "patent giants". In a blog post on October 1, COPA stated that the partners launched the "Blockchain Zone" campaign to combat patents under the control of non-practicing entities (NPEs), covering a range of technologies such as non-convertible tokens (NFTs), wallets and smart contracts. COPA said the collaboration aims to protect blockchain companies and developers from "unreasonable and expensive" legal claims by patent hoarders (NPEs), who use the high costs of court litigation to negotiate settlements.
