It’s no secret that patent infringement is one of the hottest areas in which to practice law these days. The inventor-friendly principles that governed the original United States Patent Office back when Thomas Jefferson ran it (though he personally wasn’t too much a fan of patents) are still the law today, even though the scope of prior art in most industries has expanded far beyond the point where any patent examiner could reasonably review it, much less ensure an inventor in an ex parte proceeding fairly describes it.
These days, if an inventor has enough determination, or enough funds to pay for his or her patent registration attorneys to go the whole nine yards, then they can likely obtain a patent even if their invention is at beast only arguably novel or useful. Once granted, the patent has immense value, and is protected against all but the strongest invalidity challenges thanks to the Supreme Court’s opinion in Microsoft v. i4i last summer.
As a matter of law, from the plaintiff’s perspective patent infringement claims are a sweet deal (assuming your claims aren’t totally meritless, in which case the sanctions can be quite severe). Patent infringement cases are less of an uphill climb than, say, anti-trust, drug or medical device product liability, or any claims dependent upon a class action, all of which have been under attack by the Supreme Court for years. It’s no surprise that defendants facing patent infringement claims often run scared to large corporate defense firms, asking them to pull out all the stops to defend them.
As a practical matter, though, patent infringement cases are a little more complicated than that.
