  1. I don’t really understand why everyone wants to sue everyone else so much these days? It can only be one thing… Greed.

  2. I don’t know about you guys but it seems that most patent filings are made NOT for discovering new technologies but for Business strategy. Defensive patenting. That’s sad for technology in general.
