I’m doing an initial literature search for a mechanical component, not asking for a patentability opinion. My concern is vocabulary: a recent product description might say “self-adjusting clamp,” while an older patent could describe the same mechanism using very different terms. Searching the modern phrase in Perplexity gives me a starting point, but how can I tell whether I’m exploring the underlying mechanism rather than repeatedly finding documents that share the same wording? ### What I want from the search - Alternative technical terms, with an explanation of how they relate to the mechanism. - Relevant patent classification codes that I can verify in a patent database. - Publication numbers and links to the actual documents, rather than only third-party summaries. Has anyone used Perplexity for **patent terminology expansion** and then checked the results through **patent classification searches**? I’m interested in a repeatable process, especially for older documents and translated abstracts. I wouldn’t treat an empty result as evidence that no relevant patent exists. The question is whether Perplexity can make the initial search broader without introducing plausible-sounding but unhelpful terminology. --- Original Source: https://www.mindstick.com/forum/162549/can-perplexity-help-find-older-patents-that-use-unfamiliar-terminology Copyright © MindStick Software Pvt.
