At least a decade ago since I checked but back then, “standard terms” clauses were not copyrightable, the theory being there’s an optimal way to express a legal idea and you can’t be barred from saying it that way. And a collection of such terms is basically a sampled remix.
Quoting:
“[Because] the vast majority of contracts prepared by law firms are either outright copies that aren’t entitled to copyright protection or are contracts that derive copyright protection from their status as compilations, a law firm would likely have a hard time demonstrating breach of copyright.”
And:
”It is standard practice for corporate lawyers to copy—from deal binders, the SEC’s EDGAR database, and elsewhere—and revise contracts drafted by others.... It’s a safe assumption that the vast majority of contracts are either outright copies that aren’t entitled to copyright protection or contracts that derive copyright protection from their status as compilations. Because any compilation contract would resemble countless other contracts, a law firm would likely have a hard time demonstrating breach of copyright of its compilation contract. And even if were able to do so, its damages would likely be nominal, because compiling such contracts is a relatively quick scissor-and-paste exercise. So you should feel free to copy a run-of-the- mill compilation contract, not because doing so constitutes fair use, but because the likelihood of someone knowing of that copying and having any interest in preventing it are exceedingly remote.”
