Each "first" thread for this ground separated strand by strand from the patent record worked in this section
Lead:Strand two, the steel works' "world's most advanced" language at its 1990 opening: a trade-press superlative about a plant whose process was patterned on a Japanese pilot plant — a claim about installation, not invention, and no patent for this ground stands behind it. Strand three, the residence patents themselves: Rose's sign-printer, Unger's ampoule machine, Evancich's heating tape, Huener's appliance diagnostic and Heuer's pressure transmitter are each, on their faces, improvements in crowded fields — none claims, and none is here given, a "first" of its kind. Result, printed as the searched negative the assignment allows: the patent record worked for this ground carries no contested-first device or process, and no first claim for this ground was found in the record at patent strength. Any first asserted for this ground in future must name its patent or be printed, as here, as unpatented.
