>> I can see why Rick uses Delphion <<
Too expensive for me. I use EPO, if I'm searching company name, and then double check at USPTO for anything "U.S." that might have escaped. If I'm searching for prior art, I start with USPTO and then back up with EPO.
But the EPO site is really whacko. For some reason, old stuff sometimes floats to the top. And the search interface is weak, IMO. The U.S. search interface is great, but, for applications rather than issued patents, assignees are often not there (not required, for PCT applications??).
Delphion is great. They catch everything, and present it to you in a great, easy-to-use format. I used it when it was a freebie. When they were devising their pricing, I tried to convince them that they could sell a crippled version, but searching all databases, to investors if they kept the price at a decent hurt.
(I do have a Delphion account, with lots of customization, that I didn't want to share during that trial period. I should have thought and set up a second, as Donald Duck..... if I could get around cookies, without globally disarming them.) |
