Valence Technology, Inc. v. Phostech Lithium Inc.

Valence Technology, Inc. v. Phostech Lithium Inc.

Claim 3 of Canadian Patent No. 2,395,115 is to be construed to include carbon in forms capable of effecting carbothermal reduction (including carbon residue from pyrolysed organic binders); on the evidence (weight given to Dr. Dahn) the Phostech P1 Process effects reduction by carbothermal reduction and therefore infringes claim 3. The '918 Patent is anticipated by the earlier published '129 Application and is void. The '366 Patent is not void for insufficiency nor under s.53(1) misappropriation on the evidence presented.

Patent Infringement / Trial (judgment)

Legal Issues

  1. 1 Whether Phostech's P1 Process infringes Valence's patents (notably claim 3 of Canadian Patent No. 2,395,115)
  2. 2 Construction of key claim terms including "carbon", "incorporating carbon into said mixture", "source of carbon" and "linked by being nucleated or bound to carbon"
  3. 3 Whether the reduction in the P1 Process is by carbothermal reduction (CTR) or by gaseous reductants

Ratio Decidendi

Claim 3 of Canadian Patent No. 2,395,115 is to be construed to include carbon in forms capable of effecting carbothermal reduction (including carbon residue from pyrolysed organic binders); on the evidence (weight given to Dr. Dahn) the Phostech P1 Process effects reduction by carbothermal reduction and therefore infringes claim 3. The '918 Patent is anticipated by the earlier published '129 Application and is void. The '366 Patent is not void for insufficiency nor under s.53(1) misappropriation on the evidence presented.
