Introduction

Registered Trademarks Registered trademarks, as the term implies, are words, designs, or images that have been granted trademark status by the U.S. Patent and Trademark office (USPTO). The trademark records maintained by the USPTO are publically available and can be searched in their online database. In a few cases a company may have claimed that a particular name or phrase is a registered trademark, but no corresponding registration could be located in the USPTO database. Such cases are not listed in Table 1, but are instead included in a later section listing informal trademarks. Table 1. Registered Trademarks by Company Company Mark First Use Reg.

Brands and Informal Trademarks In addition to registered trademarks, many tools are marked with words or stamped images serving as brand names or informal trademarks. In some cases, the maker may have claimed the brand as a trademark, but no corresponding registration could be found in the USPTO trademarks database. It's unclear whether these discrepancies are due to filed but rejected applications, or possibly lost or incomplete trademark records. Table 2 lists a number of word marks used as brand names or informal trademarks, with notes indicating the particular use. Table 2. Tool Brands and Informal (Unregistered) Trademarks Mark Company Notes Artisan Gamble's Auto Stores Brand used for top-quality tools, mid 1940s and later Auto-Kit J.P.

Logo Images Table 3 below shows a number of logo images taken from various tools. In some cases these are also registered trademarks (as noted in the table), but in general the logos are simply informal marks chosen by the manufacturer to identify their tools. The "Shorthand" column is just a fanciful name assigned for convenience of reference; it doesn't necessarily correspond to what the maker would have called it. Certain logos are identified in the table as "Forge Marks", meaning that they appear as a raised symbol on a forged piece, having been incised into the forging die. These marks were often used on contract manufacturing production to identify the maker. Table 3. Tool Logos with Images by Company Image Shorthand Company Forge Mark? Notes Strong-Arm Armstrong Bros.
