I am currently pursuing a deal in the manufacturing space that has a handful of patents protecting its specialized designs. Besides me reading the patent filings and assessing the runways to expiration, any advice on how to assess the strength and breadth of them? My plan would be to engage a patent attorney during the diligence process, but should I do so right after the LOI is signed? Pre/post financial DD? I am a self-funded searcher so trying to be prudent with my expense timeline while also understanding that this is a huge part of this transaction. I am meeting with the owner next week and any ideas on questions to ask him about the patents specifically are also welcome. Thank you in advance.
