My boss's trademark is being questioned . He did an intent to use application and another party filed a cancellation based on him lacking a bona fide intent . Evidence I could provide are the conversations with developers prior to filing the application which discuss the plans for the products . However , there is a very casual relationship with me and my subcontractors . I don't want to submit copies to anyone of our chat logs because I don't want to tarnish their names with them participating in such vulgar conversations . Quotes may leaked onto the web somehow during the proceedings with the opposing party citing dialogue . Can we edit out the obscenities and submit documents with a bunch of black marks through them ? Or , can I just have them sign a document swearing to the pertinent facts ?
