How to Read This Report
This page aggregates publicly available records from government agencies, court systems, and official registries into a single report for William Caspersen. Because public records are indexed by name rather than by a unique identifier, the 13 results displayed here may include information belonging to multiple individuals who share the same name — a common occurrence, especially for frequently appearing names. To determine which records belong to the person you are researching, compare the location, approximate age, and any associated details across entries. Records that share an address or overlapping timeframe are more likely to refer to the same individual.
What Each Data Category Means
Patent Filings
Patent data is drawn from the United States Patent and Trademark Office (USPTO). Being listed as an inventor on a patent means this individual is credited as having made a substantive intellectual contribution to the invention described in the patent application. Patent records include the filing date, grant date, patent number, and a description of the invention. A patent listing does not indicate that the inventor currently owns the patent rights — patents are frequently assigned to employers or transferred between entities after they are granted.
Important Limitations
Public records may contain outdated information, data entry errors, or records that belong to a different person who shares the same name as the individual you are researching. Government agencies update their records on varying schedules, and the data shown here may not reflect the most recent changes. Information on this page is provided for informational purposes only and should not be used for employment screening, tenant screening, credit decisions, or any other purpose regulated by the Fair Credit Reporting Act (FCRA). Always verify critical details through the originating government agency or official registry.

Under laws including the California Consumer Privacy Act (CCPA) and similar state privacy statutes, you may request the deletion or correction of your personal information.
