As they have often mentioned, Fireclean has applied for a patent (see exhibit A of this lawsuit for the complete application) regarding two topics: an oil composition and a method for cleaning firearms. Several years ago, they described their product in various ways as containing “at least” 25% vegetable oil by volume.
Their patent was rejected in June of 2016 and again in October of 2016, for being both too close to prior art and not being specific enough about the formula.
In April of 2017, they filed a last-ditch appeal which abandoned most of their previous claims, including all composition claims:
Instead they focused on the method portion of the patent claims, which included this line:
So Fireclean is now applying for a patent which describes a method for cleaning firearms requiring an oil composition that is a) “about 100% vegetable oil” and b) does not contain a compound which is not a vegetable oil, otherwise it would continue to conflict with the mentioned Legros patent.
Fireclean has not attached this latest 2017 patent appeal to their lawsuit against me in Arizona, or any of their previous appeals which further clarified the composition of Fireclean. Instead they present the court with, and rely upon the wording of, the original patent application from 2013, which describes “at least” 25% vegetable oil.
Just a few days ago, there was a USPTO Office Action which tentatively identified some allowable subject matter in their patent application – claims 16 and 18. Claims 16 and 18 relate to the method of treating the metal with Fireclean, either by “drying the deposited oil composition by heating at a temperature of about 100 to 400 degrees fahrenheit” (Claim 16) or “immers(ing) at a temperature of about 100 to 400 degrees fahrenheit for a period between about 10 minutes to 24 hours.” These actions require an “about 100%” vegetable oil composition.
Dropping all prior pretenses of it being “above 25% vegetable oil,” Fireclean’s latest patent application describes the product only as “about 100% vegetable oil,” – yet they continue to claim the sentence “Fireclean is probably a modern unsaturated vegetable oil virtually the same as many oils used for cooking” is something worth suing over.
