This particular patent troll has filed lawsuits with at least a dozen of my competitors in the past year. Some were voluntarily dismissed, some ongoing, rest unknown (based on my limited research skills). The patent in question involves downloading a remote database to a mobile device used as a lookup table when scanning a QR code. Yeah...
I'm a one person company and have no idea what to do.
There are definitely low-cost and pro bono (free) options out there for very small businesses. The EFF attorney referral list is a good place to start.
I'm also happy to talk it through with you if you'd like more specific information - my contact information is here: https://shawkeller.com/attorneys/andrew-e-russell/
