Canadian machinery maker Corma Inc. continues to pursue patent-infringement suits in China.
Corma, a major producer of equipment to make corrugated pipe in Concord, Ontario, recently won suits against Shanghai Jewell Machinery Co. and ERA Construction Materials Development Co., a corrugated pipe producer. Both firms are based in Shanghai, China.
In the first suit, against Shanghai Jewell, Corma prevailed in May, a little less than a year after filing the case, said Corma Executive Vice President Stefan Lupke in a telephone interview. Ruling in Corma's favor was the Shanghai Second Intermediate People's Court.
``The [patent suit] system works a lot faster in China than in North America,'' Lupke said. ``The judge takes an active role in the case. Courts are enforcing patents.''
Shanghai Jewell was infringing on a patent for Corma's mold block quick-return system, technology that helps cut down on the number of mold blocks needed in a machine. ERA was using machinery that infringed on the patent, Lupke said.
Corma holds 20 patents in China and has applied for 20 more. Since separate lawsuits are possible for each alleged infringement, Corma probably will launch more suits against Shanghai Jewell. Lupke said his firm has about eight other infringement suits in various stages.
Lupke said Corma sold ERA about a half-dozen corrugated pipe machines, but a subsequent visit to ERA's plant revealed the company was running 10 corrugated pipe machines. Convinced that Shanghai Jewell copied Corma's technology from machines in the ERA plant, Corma decided to sue.
