Inventors and Patents From the City of San Francisco

In the week ending July 30, 51 patents were granted in San Francisco. Some of the companies that received patents in San Francisco include Entropic Communications, IBM, Qualcomm, and Xerox. Others were granted patents but never got to market. While there are some similarities, the stories of these companies are often unique, but there is a common thread.


Xerox inventors and patents are an important part of the company’s history. These innovations helped Xerox solve internal problems and expand into external products. In recent years, more inventors have come forward and shared their ideas, making it easier for other companies to create a profitable product. In the past, the “my idea is the best idea ever” mentality inhibited innovation, but that is changing now. The company’s new culture is also influencing the way it develops and markets its products.

After Xerox started developing xerography in 1938, the company worked with Chet Kornei in his Astoria “laboratory”. Later, Kornei left the company to work for IBM. IBM introduced its own xerographic office copier, which was a competitor to Xerox. In April 1970, Xerox sued IBM for patent infringement, and ultimately won the lawsuit.

While Xerox executives claimed that it would take 18 months to develop a major hardware system, the team at PARC argued that they could complete it in less than three months. By collaborating with other researchers, they were able to bring their breakthrough to market.

One of the most important innovations of the 21st century was the laser printer. This new technology could produce multiple font styles and transmit documents quickly. The idea was first conceived at a research lab at Xerox’s Webster, N.Y., headquarters. Gary Starkweather and George White were two engineers who came up with the idea. They both patented their invention and credited it to two researchers: Dr. Beaman, a chemistry professor, and Dr. White, an electrical engineer, who worked as a researcher.

Entropic Communications

Juniper Networks, a company based in San Jose, California, has been awarded a patent for network labels. The technology enables users to receive multiple channels simultaneously. Its co-inventors include Arndt Joseph Mueller, Joseph B. Soriaga, and Itzhak Gurantz, who live in San Diego and Sunnyvale, Calif.

The company is also assigned a patent for a scalable header extension for wireless communications. Entropic Communications and Inventors and patents from the City of San Francisco are part of the patent process. Inventors and patents from the city of San Francisco helped the company receive this patent.

Entropic Communications has also been awarded a patent for its video streaming system. The company, located in Mountain View, Calif., was awarded the patent after a series of collaborative efforts between its co-founders. The patent application was published in the San Francisco Patent Office on Nov. 8, 2010.

Another patented invention from the San Francisco area was assigned to Apple. A patent number 8-710-233 has been assigned to the company. The technology enables users to access content through the iPhone’s speaker. This invention is currently being used by many companies, including Facebook.

Dallas-Fort Worth, San Francisco, and Detroit all had high patent portfolios. The Texas-Fort Worth area is ranked No. 9 in the nation in patents. The Texas metro has several patent-granting companies, including Accenture and Samsung. These companies have created various innovative technologies. Some examples include a system to monitor the location and speed of vehicles entering and exiting parking lots. Other patents were obtained by corporations such as Walmart, Bank of America, and Toyota.


The City of San Francisco has an incredible history of supporting innovative startups. Over the years, Qualcomm has helped more than 125 startups with everything from satellite launches to the development of AI for cutting-edge medical treatments. These startups have generated more than $200 million in funding and filed hundreds of patents, and their innovations have helped create a wide range of new products and services.

Qualcomm has developed many of the key technologies that underpin our modern communications. Its patents are a key component of every mobile device and it has been rewarded handsomely for its efforts. The company makes billions of dollars every year by selling the chips inside mobile devices. It also gets paid by other companies to use its inventions in their products.


The Inventors and Patents From the San Francisco Area show a distinct innovation pattern compared to other major US cities. The city is a hotbed of innovation, as measured by the number of patents produced per capita. Moreover, San Francisco is home to several major research institutions, such as Stanford University.

Xerox, a multinational computer company, was recently assigned a patent for a new photoreceptor layer. This technology was developed by three co-inventors, one from Los Angeles, the other from San Francisco. The patent application for this invention was filed on Jan. 25, 2012.

While the city of San Francisco is the birthplace of many inventors, the area is home to other major tech hubs. Companies such as Tesla, Lam Research, and Boston Scientific are just a few of those that are headquartered in the area. These companies were responsible for many of the patents from the city.

Patent applications from innovators outside the City of San Francisco are more likely to reach technological dead ends or be ignored. On average, 13% of patented advances from innovators outside the city are ignored in later patent applications than those from San Francisco. This suggests that San Francisco inventors and patents are often the driving force behind subsequent advances.

There are many ways to evaluate the influence of major companies on innovation in the city. One way to assess this is to compare the number of patents issued by San Francisco innovators to the number of patents issued by major technology companies. Major technology companies in San Francisco are major private employers in the area. A comparison of patent counts and quick citation levels can show whether a city has more innovators or more successful innovators than others. Similarly, a corporate analysis can examine the technology acquired by large companies in the region.


Searete has recently been assigned a patent that will enable it to manufacture hybrid vehicles. The patent, which was filed Dec. 16, 2009 (12/653,769), was created by eight co-inventors, including Roderick A. Hyde of Redmond, Wash., and Muriel Y. Ishikawa of Livermore, Calif.

Entropic Communications, Inc. has been awarded a patent for their technology – the “Entropic Communications” patent (8,566,698). The invention covers multiple channels of information that are received simultaneously. The company is based in Sunnyvale, Calif., and co-inventors include Kenneth J. Mueller, Joseph B. Soriaga, and Itzhak Gurantz.

Levi Strauss

In the 1850s, Levi Strauss arrived in the United States, where he established a business selling dry goods. He later expanded his business to San Francisco during the gold rush. As the business expanded, Levi Strauss also began to produce denim work pants and distribute the fabric to seamstresses. By the 1870s, Levi Strauss & Co., a San Francisco company, was in a position to offer wholesale services to mining operations.

Today, the famous blue jeans are synonymous with the name Levi Strauss. The company is a historical landmark in San Francisco, the birthplace of modern-day clothing. The firm was originally an importer, but it soon expanded to manufacturing in the city. Its most iconic product is the 501 blue jeans, which became synonymous with individuality and freedom.

Levi Strauss’s inventions are the products of years of hard work and innovation. The company is still in business today, and many of its employees have their roots in the Bay Area. For the first time since the 1890s, the company has donated over $2 million to fund its educational programs.

As a member of the San Francisco Board of Trade, Levi also was active in the community and became a trustee of the city’s Chamber of Commerce. His association with other merchants helped him succeed. He became a member of the Merchants Protective Association in 1879 and was elected a Trustee of the San Francisco Chamber of Commerce in 1882. In 1893, he attended the Trans Mississippi Commercial Congress meeting in Ogden, Utah. This group continued to meet each year until the 20th century.
