InvenSpan: Patents, Applications and Contribution

Demonstrating the Patent Power of Andy Van Brocklin, Principal Consultant. His portfolio of patents demonstrates performance - for your future.

Showing intense creativity and technical skill, below is a list of the Principal Consultant Andy Van Brocklin’s many granted patents and visible applications.

There can be applications filed but that are not visible. These are kept confidential by the patent office and also typically by the company filing them. It is often strategically smart to keep this information secret, as it provides early insight into a company’s technology development. The confidentiality period helps the company get an edge on competitors. It takes 18 months after the filing date before the US patent office (USPTO) publishes applications on their site.

Typically it takes around two years in total from the filing of a US patent application to receiving a grant. A prioritized application costs an additional fee, but this means the US patent office will attempt to come to a grant decision in 12 months or less. Otherwise, the average time to come to a decision (the total pendancy) is currently around 24 months as shown in the USPTO dashboard.

Many of Andy’s patent applications have been filed internationally as well as in the US. This is significant due to the large expense of filing internationally. Patents filed internationally have to be seen as highly valuable to the company filing them, due to the large financial return needed to justify the expense of filing.

A really positive and unusual aspect of Andy’s patent portfolio is the high rate of patent grants from applications. His portfolio has, from the year 2000 to date, a 78% grant to file ratio! Typically in the industry, utility patents have only a 12% grant to file ratio. What that means is that Andy’s grant to to file performance about 6.5 times the industry average. This really saves a company money, as filing each patent is costly. Having the granted patents also tends to attract enthusiastic investment. Investors see the granted patents as protecting future profits from competitors as well as additional evidence of a company’s value. Patents can also often be used as collateral for loans to enable growth.

Year after year, Andy has been reliably producing significant IP. His efforts accelerated and enabled product creation on multiple projects.
