Trademarks and Logos

This page shows tables of registered trademarks, brands and informal trademarks, and logo images used by various tool companies.

Table of Contents

Introduction

This page will present tables of trademarks, brand names, and logo images. These are closely related concepts that define the way a company presents its products to the public.

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 publicly available and can be searched in their online database. In particular, the USPTO TESS system allows structured searching of database fields, and the TSDR system retrieves trademark documents based on the registration (or serial) number.

In a few cases a company may have claimed a particular name or phrase as a registered trademark, but no corresponding registration could be found in the USPTO TESS database. In some of these cases we have been able to locate the trademark using a Google Books search for the published registration in the USPTO Patent Gazette.

In the event that no public record can be found for a claimed mark, it will be included instead in the later section listing informal trademarks.

In the table below, the Company column is generally the entity name that filed the application. In the case of name changes or mergers, trademarks representing the same product line may be listed under different entity names. The Reg. column gives the 7-digit registration number, with leading zeroes as needed to match the format expected by the USPTO TSDR system. The First Use column gives the date of the first public use of the mark, as provided by the company with the application. These dates were generally not subject to validation and may be rough estimates in some cases, especially if the trademark application was filed long after the first use date.

Note that the table is sorted first by company name, then by first use date, and finally by registration number.

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.

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.
