Meridian Manufacturing Inc. v. Concept Industries Ltd.

Meridian Manufacturing Inc. v. Concept Industries Ltd.

Summary judgment dismissed because there are genuine issues of material fact requiring trial: disputed claim construction (notably whether a 'solid inner wall' and 'formed in' are essential), conflicting expert and factual evidence about the Airpro System and the JTL Hopper and unresolved credibility and provenance issues for prior‑art evidence, such that the matters cannot be fairly decided on the affidavits and documents before the Court.

Procedural Posture

Patent Infringement and Validity (canadian Patent No. 3,036,430) / Summary Judgment Motions (dismissed)

Legal Issues

  1. 1 Whether Concept’s Airpro System infringes claims 1,2,4,5,9,11-15 of Canadian Patent No. 3,036,430
  2. 2 Whether the 430 Patent is invalid for anticipation by the JTL Force Air 360 Hopper prior to the priority date
  3. 3 Proper construction of claim terms including 'manifold duct','formed in', and 'solid inner wall'

Ratio Decidendi

Summary judgment dismissed because there are genuine issues of material fact requiring trial: disputed claim construction (notably whether a 'solid inner wall' and 'formed in' are essential), conflicting expert and factual evidence about the Airpro System and the JTL Hopper and unresolved credibility and provenance issues for prior‑art evidence, such that the matters cannot be fairly decided on the affidavits and documents before the Court.
