Patents in Emerging tech, talk by Rajiv P. Patel, Esq., Fenwick and West. Notes from O'Reilly Emerging Tech Confernece, 2003. Cory Doctorow doctorow@craphound.com -- Patents are often used by big companies to force competitors out of the market. Patent litigation, including frivolous litigation, can burn tons of cash in small companies that can't afford it. Or you can just say, "Screw it, your tech violates my patent, you're off the market." British Telecom claims it invented WiFi, the Internet, and just about everything else, and it sees this as a means of getting royalties from other companies to shore up its revenues in a sagging economy. No one challenges this extortion because it's too expensive to design new tech and it's too expensive to litigate. NTP is in the business of buying up patents and then pursuing people who use that patented tech. They've successfully sued RIM over the Blackberry, and it's in appeal now. You can be a direct infringer on a patent -- you're using someone's patent. Or you can be a contributory infringer by inducing someone to violate a patent. To find out if you're violating a patent, you need to look at the history of the patent -- what the patent office says existed in the marketplace prior to the filing of the patent application. But the UPSTO can't do an exhaustive search, and the field of prior art is worldwide, not just US. How can you figure out if BT's patent covers WiFi? A skilled practicioner of the art needs to look at the patent and the history -- whether the USPTO narrowed the patent before granting the patent. How to protect your idea from patents? There are a flood of nano patents and biotech patents being filed now. It's a land-grab. Also DRM. If you're a small company, a patent won't get you to a place where you can sue others. You don't have the assets. So how do you protect yourself? Develop a patent portfolio and strategy. You can used these to defend yourself from others. You can also use them anti-competitively against your competitors. You can show them off to investors and make them admire your technical studliness. Alternatively, you can publish every idea you have so that you can keep someone else's patent from being valid. It just need to be publicly accessible and catalogued. A defensive portfolio may protect you against like-sized competitors -- i.e., other entrepreneurial companies. If you get sued, you can threaten them with your portfolio in a countersuit. But against large companies, if won't do you much good, beyond getting a slightly better bargaining position. Developers are pissed about this and some advocate changing the patent system. But the dot-bust has resulted in numerous patent abandonments -- either through inacation or explicit abandonment. The bar for "utility" is pretty low: "anything made by man under the sun." As to novel: they USPTO only recently got access to Google -- until then, they were looking at the patent archives. But they don't find anything. It's even greyer for "obviousness" -- I have a reference that shows elements A, B and C of your claim, and this other patent claims D -- is the combination novel? You can invalidate a patent when it hits the market: when the patent is issued, if you can show "clear and convincing evidence" (less strict than "beyond a reasonable doubt," but clearer than "preponderance of evidence"). The burden for disclosure of prior art is on the filer, and if a filer fails to disclose prior art that he should have known about, he can be sued or have his patent removed. But proving intent is hard. However, attendance at a conference where the prior art was disclosed may prove this. The purpose of the patent system is to make information available to the public. We'll give you 20 years' worth of exclusivity in exchange for you telling me exactly how to duplicate it. Examiners only have 14h to consider a patent application and the USPTO is one of the few profit-centers for the govt, other than the IRS. We need to give USPTO examiners more time to examine patents.
