Sealmaster’s Patent Claims Declared Invalid

Both Vinyl Building Products (VBP) Inc. of Oakland, N.J., and Silver Line Building Products Corp. of North Brunswick, N.J., have announced that courts have affirmed that patent infringement claims made against them by Rockwood, Tenn.-based Sealmaster are invalid. Both companies appealed the claims, which involved J-rail channels, and have now prevailed.

In 1999, Sealmaster filed patent infringement claims against several companies, including Vinyl Building Products Inc., based on two integral J-channel patents. In 2000, the District Court was asked to rule that Sealmaster LLC’s patent claims were invalid. In January 2001 the District Court agreed, ruling that except for one claim all the relevant integral J-channel patent claims were invalid. It was agreed that, on appeal, the remaining claim should rise or fall with the rest of the claims held invalid by the District Court. On April 5, 2002, the Appeals Court affirmed the lower court’s decision. The Court also required Sealmaster to keep its website postings current as the company had previously sent a letter to members of the industry giving notice of its intent to pursue infringers, but neglected to post the adverse 2001 decision. According to Vinyl Building Products as of this writing, the Sealmaster’s website is no longer in operation.

In the case against Silver Line, the court granted Silver Line’s motion for summary judgment, invalidating the patents. The U.S. District Court held that windows sold by Silver Line years before the patent filings included the same integral J-rail design and therefore SealMaster’s patents were invalid.

Executives from both VBP and Silver Line applauded the decisions.

Ralph Weiss, president and chief executive officer of VBP, said, “We are very happy that the court found in our favor. We felt, and the court agreed, that the patents were invalid as being obvious in light of the technology existing long before the patents were filed. We are pleased with the decision, and we know our customers will be pleased as well.”

Silver Line chairman and chief executive officer Kenneth Silverman echoed this sentiment. “This decision is a win for Silver Line and for the window industry in general,” he said. “We are gratified not only that the Court saw the logic in our argument, but more importantly, that the judicial system worked in a manner that brings this matter to a complete and unambiguous conclusion.”

Strybuc Industries of Sharon Hill, Pa., recently announced its acquisition of Window Com-ponents Manufacturer Inc. (WCM) and Wind-Door Parts (WDP).

Currently, WCM also manufactures injection-molded parts, stamped items, extrusions, block and tackle balances and offers a full-time line of packaged and carded items for display.

Azon Celebrates 25 Years

The Azon family of companies, headquartered in Kalamazoo, Mich., was founded 25 years ago with the goal of assisting the world in energy conservation.
James and Ruth Dunstan founded Azon in 1977, taking an immerging pour and debridge technology and introducing it to the marketplace. The technology required a marriage of chemicals and the proper form of dispensing them in the aluminum extrusion through a full range of equipment, said company officials.

Azon also manufactures aluminum thermal barrier windows, doors and curtainwall, as well as Warm-Light™, a structural, warm-edge spacer used in the construction of insulating glass, according to the company. The combination of aluminum and polyurethane is what gives Warm-Light its strength and energy savings—both characteristics that are important in any building and climate, said the company.

Wood Windows Remain in High Demand

According to the Window & Door Manufacturers Association (WDMA), the stronger-than-anticipated housing market means wood windows will continue to maintain a strong market share, and manufacturers are capitalizing on that by introducing new styles, hardware and price points.

“Vinyl and PVC windows have seen remarkable growth in recent years, but we believe that the fast growth had ended, and their rise has stabilized,” said Alan Campbell, WDMA president. “There always is a demand for wood windows, especially in the upper-end market, but now more so in the mid-range as well.” Manufacturers have responded to this consumer interest by introducing products with more affordable pricing but that still retain the key benefits offered by high-end wood windows.
Energy efficiency remains a key selling point, Campbell adds. “There already is a strong demand for highly energy-efficient windows, and that will increase. There is growing sophistication and understanding among consumers, and their expectations for what their windows can do is rising as energy prices rise,” said Campbell.
