How does something like this avoid IP theft/infringement cases? By all accounts it’s functionally the same thing as DocuSign? I ask because I am genuinely curious and hoping to learn a bit about IP law.
What kind of issue do you have in mind? By all accounts, the functionality or OpenOffice, LibreOffice, and Google’s suite are the same as Microsoft Office. There’s no theft unless they _actually stole intellectual property_
Theft is theft, no reason to get IP law involved.
Infringement can happen without intent. I don't know who would be liable, the open source company with little revenue, or the customers who are just using the software.
