A newspaper article (from an unidentified newspaper clipping, date unknown) indicated that at some point a New York firm of Patent Attorneys along with an expert draftsman and auto specialist visited Clough to sum up work in his laboratory on experiments on several years of work in the perfection of a new automobile tire. Patents were to be taken and it was expected the new tire would run 25,000 miles without blow-outs or replacement. No evidence of a patent application has been found.
