One of the major problems with patent law is that, in the case that when you are sued by a patent troll, the burden of proof that you did not infringe on the patent is actually on the defendant, which means you have to prove that you do not infringe on the patent they're suing you on.
Uno de los principales problemas de la ley de patentes es que si un troll de patentes nos demanda, la carga de la prueba de si uno infringió la patente está a cargo del defensor, o sea que uno tiene que demostrar que no infringe la patente por la que lo demandan.
