Stephan Lerman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20260085167
    Abstract: An article is comprised of a thermoset polymer having a dye sublimation image in a layer attached or integral to a surface of the thermoset polymer, wherein at least a portion of the thermoset polymer is a foam. The foam article may be made by pretreating a thermoset organic polymer foam to a temperature of 100° C. to about 250° C. for a time sufficient to stabilize the thermoset polymer and dye sublimating an image into a layer of the pretreated thermoset foam. The foam article having the dye sublimation image may be used for applications having aesthetic or structural requirements such as railing, decking or fences.

  • Publication number: 20240367452
    Abstract: An article is comprised of a composite substrate comprising a non-polar thermoplastic polymer such as a polyolefin or polyvinyl chloride and a filler having polar groups, the composite having a dye sublimation image in a layer adhered or integral to a surface of the composite. The article may be made by exposing the aforementioned composite substrate to a temperature above 100° C., which is typically above the melt temperature of the non-polar thermoplastic polymer, to about 250° C. and pressing a dye sublimation film onto the composite substrate for a time to imprint the dye sublimation image into the accepting layer forming the article. The article may be used for applications having aesthetic or structural requirements in the construction arts such as railing, decking or fencing.
