2. **Validity of Patents**: CBS contended that the patents in question were invalid based on prior art and argued that they did not infringe on Helferich's patents.
3. **Damages**: Helferich sought monetary damages for the alleged infringement, including a reasonable royalty based on CBS’s profits derived from the infringing technologies.
**Legal Findings:**
- The court examined the validity of Helferich's patents in the context of the claims made, including an analysis of the relevant prior art.
- Expert testimony and technical documents were reviewed to determine whether CBS’s products fell under the scope of Helferich's patents.
- Insights into the economic implications of the alleged infringement were presented, focusing on the extent of CBS's use of the technology and its financial impact.
**Outcome:**
The court ultimately ruled in favor of CBS Interactive, finding that Helferich's patents were invalidated on the grounds of prior art, and therefore, no infringement occurred. The ruling underscored the importance of thorough patent examination and the necessity for patent holders to present robust evidence of both validity and infringement.
**Significance:**
This case highlights the challenges faced by patent holders in the technology sector, particularly in enforcing patents related to rapidly evolving digital platforms and advertising technologies.
