MEMORANDUM OPINION AND ORDER

Figure on page 1 of the opinion

The Court issues this claim construction opinion and order to construe terms that the parties

contend are either in dispute or otherwise require construction.

The plaintiffs, Produits Berger S.A. and Lampe Berger USA, Inc. (“Plaintiffs”), claim that

avid M. Schemenauer and The Marshall Group, Inc. (“Defendants”) infringe six claims defendants D

in the patent-in-suit, U.S. Patent No. 6,537,061 (“the ‘061 patent”).

For the reasons set forth below, the Court construes the identified claims in accordance with

the rulings made in this opinion.

The Patent-In-Suit

cribes an invention concerning a catalytic combustion afterburner made of The abstract des

material, comprising in its lower part a substantially axial cavity for receiving a taper porous

convey to the burner a combustible liquid, and in its upper part an annular peripheral designed to

g a catalyst and enclosing a central zone without catalyst forming a vaporizing zone. The zone bearin

in its upper part an open duct, communicating the cavity upper part with the afterburner comprises

outside air.

2Applicable Law

“It is a ‘bedrock principle’ of patent law that ‘the claims of a patent define the invention to

which the patentee is entitled the right to exclude.” Phillips v. AWH Corp., 415 F.3d 1303, 1312

(Fed. Cir. 2005) (en banc) (quoting Innova/Pure Water Inc. v. Safari Water Filtration Sys., Inc., 381

F.3d 1111, 1115 (Fed. Cir. 2004)). In claim construction, courts examine the patent’s intrinsic

evidence to define the patented invention’s scope. See id.; C.R. Bard, Inc, v. U.S. Surgical Corp.,

388 F.3d 858, 861 (Fed. Cir. 2004); Bell Atl. Network Servs., Inc. v. Covad Communications Group,

Inc., 262 F.3d 1258, 1267 (Fed. Cir. 2001). This intrinsic evidence includes the claims themselves,

The Terms

The Court adopts the parties’ construction where agreed. The Court will construe the

remaining disputed terms which the parties agree require construction: (1) “With a wick to convey

a combustible liquid to the burner”; (2) the “Separated” Limitation; (3) “Annular Peripheral Zone”;

Open Channel”; (5) Claim 5; (6) Claim 7; (7) Claim 8; (8) Claim 12; (9) Claim 14 — the (4) “The
