## Questions

### What is the difference between RPX and a traditional patent licensing firm?

Traditional licensing firms assert patents to extract royalties, often through litigation. RPX acquires patents pre-litigation to remove them from the PAE market, using a subscription model funded by its clients. This defensive posture aligns the firm with operating companies rather than against them.

### Does RPX own patents outright?

Yes, RPX purchases and holds title to patents, either singly or in portfolios, and its subscribers receive a license to the entire RPX patent pool. The firm also maintains a division, RPX Litigation Insurance, which provides legal fee coverage for patent defense.

### How does RPX source its patents?

RPX sources patents directly from operating companies, universities, inventors, and the secondary market via brokers and auctions. The firm's deal flow includes court-ordered auctions from bankrupt entities and bulk portfolio acquisitions from corporate sellers (per company filings).
