I would like to ask a question here 'cause I'm wondering.
Isn't there an abandoned patent law somewhere on the books?
How can they enforce a claim after abandoned especially when they are not the original patent holders?
I seem to have come across something like this when doing research a few years ago.
These Acacia people have abandoned these patents for at least 5 (maybe more) years while the Internet grew and are now trying to collect on the abandoned claim.
If these patents (If they apply at all) would have been enforced since the begining just maybe the companies being sued would have developed other technologies to use instead.
Food for thought!!!
