I released an app in Apple's App Store in 2010, way back when there were only 100,000 apps that existed. It was called Real Date Wheel, and it was a functional datewheel that you could rotate the wheel to determine a future date when for instance your injection molding or stamping tool would be built; essentially a project management tool that existed in physical form for a long time. Here's a picture of what a date wheel looks like.

I was contacted by a woman who claimed I was infringing on her trademark for Date Wheel. I was using Real (TM) Date Wheel. She claimed that by using the word real, I was implying her software solution wasn't real. I nearly fell out of my chair.
I wrote two letters that shut her down. I had previously studied to take the patent bar exam, so I have a mind for intellectual property and spent $180K on personal patents as well. I knew you cannot trademark a common word or phrase.
Unless this company applied for the trademark before the 2009 white paper, bitcoin has become a common word in the lexicon and therefore can't be trademarked. I highly doubt this frivolous case will stand up in court. But it's no surprise some lazy and greedy company wants to capitalize on this.
