The year 2008 saw some significant decisions issued by the Supreme Court and the Federal Circuit Court of Appeals on patent law questions. In this article, we will highlight the key points of some of these decisions.
1. Patent Licensing and the Exhaustion Doctrine.
Under the doctrine of patent exhaustion, a patent owner's patent rights in an article embodying a patent invention end once an authorized sale of the item occurs. In Quanta Computer, Inc. v. LG Electronics, Inc. the Supreme Court considered how this doctrine applies in a licensing situation. Computer manufacturer Quanta purchased Intel chips and installed these chips in computers manufactured for others. LG owns several patents concerning these chips and licensed Intel to manufacture chips with the patented technology. LG did not license Intel's customers to install the chips in machines they were manufacturing for others. When LG sued Quanta for patent infringement, asserting that combination of the Intel chip and non-Intel components infringed LG's patents, Quanta argued that LG's patent rights were exhausted once Intel, as LG's licensee, made an authorized sale of the chips to Quanta. The Supreme Court agreed.
2. Patentability of Business Method Claims.
In In re Bilski the Federal Circuit addressed the question of the standard for review of proposed patent claims covering business methods. Business method claims are often utilized to protect a method of how a business performs an operation or procedure. Prior to Bilski, several different tests for patentability of these types of claims were being utilized by the Patent Office, such as the "machine or transformation" test, the "technological arts" test and the "useful, concrete, and tangible" test. Bilski clarified the issue by deciding that the "machine or transformation" test is the proper test. The "machine or transformation" test requires that a business method claim be tied to a particular machine (e.g., software code to be executed by a computer), or transform a tangible article. Without such ties, the claim is invalid.
3. Test for Infringement of Design Patents.
Prior to the Federal Circuit's decision in Egyptian Goddess v. Swisa, Inc., courts used two tests to determine infringement of a design patent. The first of these tests was the "ordinary observer" test, which requires a comparison between the accused design and the patented design, and then consideration of any applicable prior art designs. The second test was the "points of novelty" test, which focused on the points of novelty of the accused- and patented designs. Analysis under the points of novelty was often complicated if there were multiple points of novelty or if the point of novelty was a combination of design elements. Egyptian Goddess decided that ordinary observer test was the proper test for evaluating design patent infringement claims. This decision arguably increases the value of design patents by making claims of infringement less burdensome to support.
4. Opinion of Patent Counsel in Inducement-of-Infringement Claims.
An allegation of inducement-to-infringe requires that the patentee show that one has enabled another to infringe a patent and requires that the patentee establish that: (1) there has been direct infringement of the patent claims, and (2) the alleged infringer knowingly induced infringement by another and possessed specific intent to encourage such infringement. In Broadcom Corp. v. Qualcomm, Inc., the Federal Circuit addressed the issue of how opinions of counsel factor into inducement to infringe allegations.
Opinions of counsel in patent infringement claims are often obtained to provide a defense to a claim of willful infringement, which if shown could significantly increase monetary damages awarded to the patentee. A 2007 Federal Circuit decision appeared to pull back the importance and necessity of opinions of counsel in such claims, indicating that other evidence could be as probative on the issue. In Broadcom, however, the Federal Circuit held that a jury could consider evidence of whether an alleged infringer obtained an opinion of counsel in determining liability on an inducement-of-infringement claim, thus renewing the importance of these opinion letters in defending such a claim.
Qualcomm had not obtained opinions of counsel on the issue of patent infringement, but was not found liable on the willfulness count. Qualcomm unsuccessfully argued that it couldn't be found to have induced infringement if it wasn't liable for intentionally infringing, since the bar is higher to prove inducement. The Federal Circuit disagreed, instead finding that inducement can be found even without a showing of willfulness. The Court stated that because opinion-of-counsel evidence, along with other factors, may reflect whether the accused infringer "knew or should have known" that its actions would cause another to directly infringe, such evidence remains relevant to the second prong of the intent analysis in an inducement claim.
5. Direct Infringement of Method Claims.
A "method" claim in a patent includes a list of steps to perform the claimed invention. These types of claims can be written to require that the various steps be performed by different entities, which raises issues regarding proving an allegation for direct infringement of a method claim when there are multiple parties involved. In Muniaction v. Thomson Corp., the Federal Circuit addressed this issue by deciding that unless one of the parties exercises control over entire process, such an allegation could not be supported. The Court found that such control was not evident when the defendant auction company received data and determined the winning bidder, but did not control the actions taken by the bidders in submitting bid information.
