Kenall Manufacturing v. H.E. Williams, 9-CV-1284, Slip Op. (N.D. Ill. Feb. 1, 2013)
Kenall filed this suit against H.E. Williams alleging infringement of U.S. Pat. Nos. 6,984,055 and 7,494,241. Both patents deal with light fixtures.
The Court construed the following terms in a 34 page opinion:

- “isolated (raceway)”: Construed as “a distinct space for passing media – like wiring – within a light fixture that is separated along its entire length by some kind of physical barrier or means so that the wiring which runs through it is separated from the wiring that traverses another raceway.”
- “housing”: Construed as “a structure that supports or contains lighting fixture components.”
- “endplate”: Construed as “a structure for attachment to a lengthwise end of a light fixture housing.”
- “sealing”: Construed as “joining two structures in a manner that prevents the passage of fluids between the two structures.”
- “mating:” Construed as “fitting two parts together via corresponding shapes.”
- “bridge:” Construed as “a distinct structure adapted for coupling multiple housing by those housings’ endplates.”
- “adapted for attachment to any one of” & “attachable to any one of”: Construed as attachable to all of the items in the list following these terms.
