Brian Higgins’s Maryland IP Law Blog post about the progeny of In re Seagate, 497 F.3d 1360 (Fed. Cir. 2007), inspired me to do follow up posts identifying Northern District cases discussing recent major IP decisions — click here for my post on injunctions after eBay Inc. v. MercExchange, L.L.C., 126 S.Ct. 1837, 164 L.Ed.2d 641 (2006). There have been a number of obviousness decisions in the Northern District since KSR Int’l Co. v. Teleflex Inc., __ U.S. __, 127 S.Ct. 1727 (2007). Here they are:*
Abbott Labs. v. Sandoz, Inc., No. 05 C 5373, 2007 WL 1549498 (N.D. Ill. May 24, 2007) (Coar, J.). — Holding that the Court’s pre-KSR analysis need not be reconsidered in light of KSR because an element was missing from the prior art, regardless of what standard was used.
Herman Miller, Inc. v. Teknion Corp., No. 05 C 2761, 2007 WL 2230042 (N.D. Ill. Jul. 30, 2007) (Gettleman, J.). — Noting that, in light of KSR, plaintiff issued a statement of non-liability and certain patents were removed from the suit.
Lexion Medical, LLC v. Northgate Techs., Inc., No. 04 C 5705, Slip Op. (N.D. Ill. Jun. 8, 2007). — Holding that the pre-KSR jury’s decision would not have changed if given a KSR obviousness instruction.
These opinions suggest that KSR is not changing obviousness law in the Northern District much. I suspect that is not true. Once we have a larger sample of cases, including more where the initial analysis was not done pre-KSR, we will see more patents held invalid based upon obviousness.
* A brief note on methodology: this was not a thorough study and does not include cases that granted or denied injunctions without discussion. For a more complete list of post-KSR decisions nationwide, go to the Fire of Genius.

Fed. Cir.
Claim Construction Reversal Requires New Trial
Black & Decker, Inc. v. Robert Bosch Tool Corp., No. 2007-1243, 1244, Slip Op. (Fed. Cir. Jan. 7, 2008).*
The Federal Circuit affirmed the Northern District jury’s obviousness verdict, and Judge St. Eve’s denial of defendant’s inequitable conduct claim. But the Federal Circuit reversed the Northern District’s construction of “power conversion circuit” and remanded for further proceedings and, perhaps, a new trial.** The Federal Circuit held that the Northern District relied largely upon claim differentiation for its construction and, in the process, gave the patent scope beyond the disclosed invention.
The Federal Circuit held that the Northern District’s pre-KSR obviousness jury instruction was not reversible because defendants identified no evidence in the record that supported an obviousness finding even under the broader KSR standard.

** The Court scheduled a status conference early next week. We may learn at that conference whether a new trial is being scheduled or whether summary judgment will be briefed or a settlement conference scheduled first.

Construction Reversed Despite “Commendable” Analysis
Chamberlain Group, Inc. v. Johnson Controls Interiors LLC, No. 2007-1314-1467, Slip Op. (Fed. Cir. Feb. 19, 2008).
The Federal Circuit reversed Judge Moran’s construction of “binary code” and, therefore, reversed the limited preliminary injunction entered by the Northern District – click here and here for the Blog’s posts regarding the injunction. The Northern District construed “binary code” as a code represented by two values, but not necessarily a binary number – click here and here for the Blog’s posts regarding the Northern District’s claim and construction opinions. The Federal Circuit praised the Northern District’s claim construction analysis, but reversed the construction:
The district court commendably strove to follow this court’s rules for claim construction. See Phillips, 415 F.3d at 1318-19. In this regard, the trial court weighed the intrinsic evidence along with the extrinsic evidence and properly sought to avoid importing a limitation from the specification into the claims. See id. Nonetheless, this court discerns that the ‘544 patent specification gives particular limiting meanings to the language in the claims.
The Federal Circuit held that “binary code” required a binary (or base two) number. Otherwise, any values would meet the limitation because all values, whether in base two, three, the more standard ten or any other, are represented by computers using two values – 1 and 0. Because the revised claim construction called into question the Northern District’s likelihood of success analysis, the Federal Circuit reversed the preliminary injunction.

Reliance Upon Fed. Cir.’s Cursory Potential Invalidity Statements Avoids Willfulness
Abbott Labs. v. Sandoz, Inc., No. 05 C 5373, 2007 WL 4287503 (N.D. Ill. Dec. 4, 2007) (Coar, J.).*
Judge Coar granted defendant Sandoz’s Fed. R. Civ. P. 12(b)(6) motion to dismiss or in the alternative Fed. R. Civ. P. 12(c) motion for judgment on the pleadings, dismissing plaintiff Abbott’s willfulness claims Abbott alleged that Sandoz willfully infringed Abbott’s patent related to an extended release antibiotic (clarithromycin, an erythromycin derivative which Abbott markets as Biaxin XL). At the time Sandoz entered the market with its generic version of Biaxin XL, the Federal Circuit had issued an opinion based upon an interlocutory appeal of a temporary restraining order, which included statements that Abbott’s patent was susceptible to invalidity and unenforceability argument. The Court held that Sandoz’s reliance on that opinion, regardless of the limited record it was based upon or its non-final nature was objectively reasonable, well above the In re Seagate objective recklessness standard.

Federal Circuit Further Defines Ordinary Observer Test
Arminak & Assocs., Inc. v. Saint-Gobain Calmar, Inc., No. 06-1561, Slip Op. (Fed. Cir. Sept. 12, 2007) (Holderman, C.J., sitting by designation.).*
On behalf of Chief Judge Michel and Judge Gajarsa, the Northern District’s Chief Judge Holderman affirmed C.D. California’s holding that declaratory judgment plaintiffs’ (“Arminak”) “AA Trigger” shroud design for a spray bottle did not infringe declaratory judgment defendant’s (“Calmar”) design patents covering certain design elements of shrouds. The main issue, and one of first impression, was whether the “ordinary observer” for purposes of design patent infringement should be the end-user/purchaser of spray bottles or the industrial purchaser that buys triggers or shrouds for assembly into a finished spray bottle product. The district court held that the ordinary observer was the industrial purchaser and the evidence clearly established that industrial purchasers would not be confused by similarities between Arminak’s and Calmar’s patented shrouds. Calmar argued, however, that the Supreme Court in Gorham Mfg. Co. v. White, 81 U.S. 511 (1871), expressly excluded experts from being ordinary observers and that, therefore, retail purchasers had to be the ordinary observer. But the Federal Circuit noted that did not sell shrouds or fully assembled spray bottles including their respective shrouds to retail purchasers. The parties sell shrouds to industrial purchasers. Industrial purchasers, therefore, are the appropriate population of ordinary observers. The ordinary observer is:
A person who is either a purchaser or, or sufficiently interested in, the item that displays the patented designs and who has the capability of making a reasonably discerning decision when observing the accused item’s design whether the accused item is substantially the same as the item claimed in the design patent.
* This is not an appeal from the Northern District, but I am covering it because Chief Judge Holderman authored the Opinion. Thanks to Dennis Crouch at Patently-O for bringing the case to my attention.

First Post-KSR Fed. Cir. Obviousness Analysis
Leapfrog Enterprises, Inc. v. Fisher-Price, Inc., No. 06-1402, Slip Op. (Fed. Cir. May 9, 2007).
The Federal Circuit issued its first opinion analyzing an obviousness determination based upon the Supreme Court decision in KSR v. Teleflex, 550 U.S. __, 2007 WL 1237837 (2007). The Court affirmed the district court’s holding that the claim was invalid based upon obviousness and explained that obviousness is not determined by “a rigid formula disassociated from the consideration of the facts of a case.” You can download a copy of the Federal Circuit’s decision here.
