Here's a good one.
Smart Parts bought the technology for a specific paintball gun. One that used electronics to operate the function of the gun. That being, open and close bolt, manage air flow, and start the cycle (AKA a switch).
That was 1997. In 2002, they were able to wordsmith the patent, and get the patent reapproved, for it to cover any paintball gun that used any type of electronics to facilitate the launching of a paintball. This encompassed designs for a grip that contained a circuit board, as well as completely different designs that simply fit the description but were nothing like original patent.
Now, there are three big compaines that make electronic paintball guns, and a handful of ones small ones that make electrical components that connect to paintball guns. Smart Parts (a paintball jugernautt sized company) served a mom and pop custom gun shop (AKA can't afford a lawyer) with a cease and desist order, then sued them into coughing up an amount of money per each gun they sell. This did two things. If effectively put the mom and pop shop out of business and set precedent to enforce the patent. Smart Parts has now served the other two big compaines with the same cease and desist order. Except now, they have precedent and the big compaines are screwed.
So, you want to talk about Stupid patents and Lawyers screwing Joe Public?
