Hello. Is NellyMoser Asao's patent expired? If not, when will NellyMoser Asao's patent expire?
I am not a lawyer, so this is not legal advice, however:
Looking at NellyMoser's patent portfolio and all the patents by the inventors of their associated patent filings, all of the patents appear to be expired due to a failure to pay maintenance fees to the USPTO as of about 2009. Even if that hadn't been the case, it seems like they would have expired around December 2023.
Thanks.
