61 Inventors and Patents From the City of Mountain View

Mountain View inventors and entrepreneurs recently received 61 patents in one week. The largest gap between filing and grant was 3,448 days. Kimber Lockhart filed her patent application on Aug. 17, 2012, and received approval on Jan. 25, 2022. While patents are crucial for innovation, they are not a guarantee of success.

PTMT counts inventors by regional component area

The PTMT database provides counts by regional component area of inventors in the United States, as well as inventors in other countries. This database is part of the Economics literature database. For example, the count of inventors in “selected environment-related technologies” is less than the sum of all sub-components. This is because inventions are usually classified into more than one technology class. The counts are based on all of these sub-components.

PTMT drills down to micro/metropolitan area level

PTMT has improved its methods for aggregating inventors and patents from a given area. By drilling down to the micro/metropolitan area level, the aggregation process is more efficient and reduces the problem of identifying inventors by unique locations. PTMT’s reports profile inventors and patents by city, state, and first-named inventor.

This method uses data from the United States Patent and Trademark Office to determine patent inventors’ geographic location. This database matches inventors with multiple cities, counties, and regional component areas. Where the inventors’ cities and counties are not identical, the inventors’ counts are divided equally among these areas.

PTMT matches inventors and patents to U.S. counties using a modified FIPS 55-3 standard. PTMT considered using GNIS data for the residence matching of inventors but decided to use USPS files because they provided a higher match percentage.

PTMT counts inventors by U.S. state or territory of residence

The U.S. patent database tracks inventors’ residency by U.S. state or territory at the time of grant. While this information is not readily available for each inventor, there is some regional component area data available for each inventor. These regional component areas are associated with each inventor’s first-named city. PTMT manually matches the data to the appropriate area.

The data collected for the PTMT contain data on inventors’ addresses, including street address and zip code. While most inventors supply their full street address, the zip code file may be unavailable. While this information is readily usable for computer aggregations, it is not available in image format.

The average number of patents awarded to each inventor is around three. If an inventor has more than three patents, he or she is considered a prolific inventor. The threshold for this category is fifteen patents, but the number of patents is arbitrary, at least for the purposes of this ranking. Nevertheless, it does provide some insights into the distribution of inventions.

While women inventors are not a dominant force in history, their contribution to innovation is modest. According to the Wilson Sonsini Goodrich & Rosati law firm, women earned a total of 8596 patents from 1890 to 2010, or 0.8 percent of all U.S. patents in that period.

The most prolific inventors are ranked by the number of utility patents awarded. Unpatented inventions are not counted. The list does not attempt to measure the significance of an inventor’s inventions, as they are usually not recognized until decades after they have been patented.

PTMT was unable to determine a U.S. state or territory of residence

While many inventors list their city of residence, PTMT was not able to determine a specific state or territory for these patents. Therefore, these inventors are listed as “Undetermined County” or “U.S. Unspecified Region.” PTMT has been working to improve its methods of determining inventors’ locations. It will continue to update the database as new data becomes available.

USPS files are used to match inventors’ city and state of residence with the counties and states where they reside. However, a place name can be associated with the wrong county, which can cause inaccuracies in the matching process. In addition, the USPS file only matches a primary county and one or more city names, which means that smaller place names can be missed.

PTMT was unable to identify a U.S. state or territory of residence

The city is not a U.S. state or territory, but it does contain multiple inventors. In the PTMT patent database, the cities of the inventors are matched with multiple regional component areas. In this way, the inventors from different cities are counted equally.

In the past, PTMT has identified the residence of inventors based on their city and state of residence. However, this information is limited and the U.S. Post Office does not provide this information for some cities.

However, PTMT has recently focused on U.S. state and county level aggregations, which have largely mitigated this issue. The methodology used by PTMT has some limitations and PTMT has produced a set of regional component area tables. Currently, about 12 percent of first-named inventors are associated with more than one regional component area.
