Where do you find copies of the patents? The following site gives the inventors, filing date and first claim etc. The US Patent Office just announced that all patents should be on the Web late next year in full (free). The filing date may be later than the priority date of the patent if it is a division of the original. patents.ibm.com The easiest way to find patents like this is to go to this site and input the company's name as the assignee. Doing this, Affymetrix has 11, its predecessor Affymax 58 and Hyseq only 3. I don't know if Hyseq had a predecessor company that has earlier patents because the earliest filing I found for Hyseq was 1995 and they are claiming patented art far earlier than that. The article posted today on this board by Jay Brandes washingtonpost.com provides additional information about 14 approved patents that AFFX will have coming out within probably the next 6 months or less time. One major competitor [of Packard Instruments] in the biochip arena, California-based Affymetrix Inc., said that the technology the Argonne group claims to have pioneered may in fact infringe on Affymetrix patents. Affymetrix's senior vice president and general counsel, Vern Norviel, said his company has 14 patents that have been granted but not yet published. So, he said, he finds it hard to believe the Argonne group knows for certain that its process is a breakthrough. Istavan [of Packard Instruments] said there are major differences between his group's biochip and Affymetrix's. The new chip, he said, analyzes longer strands of genetic material and can do so in three dimensions.

I use these two web sites: patents.ibm.com micropat.com Micropatent charges you five dollars per patent, but they give you a pdf file so you can print it. They also have European PCT applications, which IBM doesn't. The ibm server is free, but it only gives you one page at a time. It's a pain if you want to print out and read the whole thing. They also have only US patents. It's by far the best system for searching though. It hyperlinks patent references and lets you know which patents reference the one you are looking at. I think this is the affymetrix patent Richard was referring to: patents.ibm.com Jim
