Trademarks and Logos

Table of Contents

Introduction

This page will present tables of registered trademarks, brand names and informal trademarks, and logo images used by various tool companies. 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 and then 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 has yet been found in the USPTO trademarks database or in the Official Gazette publication.

Over time, we expect to be able to locate some of the missing trademark records, and entries in the "Brands" table will move to the "Trademarks" table. This has happened recently (2021, 2022) as brands Artisan, Barcaloy, HEXALL, Motiv, and VOLUME have all been found to be registered trademarks.

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 extracted from tool photographs, trademark filings, or published sources. 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 shows the names we've assigned for convenience of reference, which have been chosen carefully to allow the logo images to be found easily using an index search. Most logos consist of one or more letters in a geometric outline or other recognizable shape, and our naming convention tags the image with XYZ-Outline, where "XYZ" are the observed letters, and Outline is the enclosing shape. (If there's no obvious outline, we have appended "-Logo" to the letters.)

The "Company" column will generally identify the company using the logo and link to our article for the company. Logos for unknown forge-marks or tools from unknown makers will point to a section where we've gathered whatever information is available.

In a few cases "Multiple Uses" will appear instead of a specific company name, indicating that the same (or nearly identical) logo was used by multiple companies. For these cases the site index under "Logo Images" will have links to the "Tool Identification" sections of the companies known to use the mark.

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.

Our intention is that this table of logo images (along with the tables of trademarks and brands) should be sufficient to identify the tools made by any of the companies noted on this site, within the scope of our coverage. If any of our readers have found additional logos that should be added, please let us know via email.

Tips for Searching

If you're trying to identify an unknown logo, it may be faster to use an index search rather than looking through all of the images. Try entering the observed letters followed by a dash and the outline shape in the search box. (Popular outlines are Triangle, Diamond, Hex, Oval, and Circle, plus Shield and Horseshoe.)

If you're not sure of the order of the letters, a search for the outline shape followed by "image" will show all logos with that outline. For example, searching for "circle image" will show all of the logos with text in a circle.

References and Resources

The information in the registered trademarks table was obtained from the U.S. Patents and Trademarks Office (USPTO) at uspto.gov [External Link]. The specific systems used were the "TESS" database for structured searches and the "TSDR" document retrieval system. Note however that in recent years the USPTO has been deleting historical trademark records from their online database, and these systems are now basically useless for historical research.

Trademark Research using Hathi Trust

For trademark research the best current alternative is to search back issues of the USPTO Official Gazette, which have been digitized by Google Books. If nothing is known about a potential trademark, a starting search for company names or trademark terms can be done using Google Books. (It may help to throw in "gazette" or "trademark" as a search term.)

Once a publication date or registration date is known, specific volumes of the Official Gazette can be searched at the Hathi Trust Digital Library [External Link]. The Hathi Trust provides full text search facilities, but since the back issues are grouped by month, the search will be tedious unless the date or volume are known.
