In the website of a newly launched social media app, they display a flow diagram to their business model and then have the "USPTO patent pending" logo next to it. The actual patent number is not displayed, but I am sure the company only owns one patent.
The flow diagram is a super simplified version of what is covered.
The actual patent has already been allowed, but the website has not updated that fact.
The flow diagram can only be interpreted as a misrepresentation of what is covered in the patent.
Is this illegal?
Can someone sue and under what circumstances?
