A lot of people don’t realize that according to U.S. patent law that “whoever without authority makes, uses, offers to sell, or sells any patented invention,…(snip)…infringes the patent.” (35 US Code, Part III, Chapter 28). In fact purchasers of items that infringe a patent can be sued and held liable for damages. This is not new.
There is a special case for non-commercial consumers who purchased an infringing item in good faith. According to the UCC (Uniform Commercial Code), purchasers who meet the above definition must be indemnified by the manufacturer and/or the entity that sold them the item. The consumer can still be sued, but the seller must make good any damage done to the consumer, including legal fees.
In the case of Hp, Dell, etc., Intergraph probably has a very strong case, especially since Intel lost (and lost rather badly at that). Now whether or not Intergraph can show that they deserve any damages, after they have already collected a kings ransom from Intel, is another question.
While the whole patent system has some serious faults, this definition of infringement and who is liable to whom, is no more illogical than the rest of our federal civil system.

Oh, and by the way, if you will read the first sentence of Title 35 again, you will see that there is no exception for people to make or use patents for their own use. The Urban Legend that ‘it’s OK to use a patent as long as I don’t sell it’ is absolutely wrong and just that, an Urban Legend. If you make it or use it (the patented invention), you are infringing!
