According to the Maryland Intellectual Property Law Blog, Maryland has seen only 10 patent lawsuits in 2010. Incredibly, there have already been 265 patent lawsuits in Texas. There are more patents in Texas than in Maryland. Maryland inventors received almost as many patents in the first half of 2010.
Drug companies, who are anti-lawsuits until they want to file one, are frequently parties in patent lawsuits involving one drug company accusing another of reverse engineering or copying of drugs.
