Please go to US Inventor, https://www.usinventor.org & learn about Josh Malone (Bunch of Balloons) and what the PTAB is doing to legitimate inventors who's hard fought and paid for patents are getting 'nullified' by companies who just don't want to pay a reasonable licensing fee to use their invention. This is a very legitimate organization doing a lot on Capital Hill to help. They have a lot of info and encourage people to reach out to your Congressmen and Senators; loud voices everywhere sometimes break through.
