Freedom to Operate/Commercialise
• The ability to experiment, manufacture and/or commercialise your invention without the impermissive use of a third parties patented inventions
• No relevant unexpired, enforceable patents in locations targeted
• No relevant patent applications that could become a barrier

Freedom to Operate Analyses
• Professional searcher • Patent attorney• Never 100% certainty• Time consuming• Expensive• Third parties still require
– warranties– indemnities– stacking royalties
SO WHY BOTHER!
![Page 9: 2.30pm Jones Michelle - rsc.orgProf. Sir Tom Blundell, Harren Jhoti, Prof. Chris Abell, Roberto Solari • Internally generated pipeline of novel molecularly targeted oncology drugs](https://reader033.fdocuments.us/reader033/viewer/2022060719/607f9316605ab11ec1001cbc/html5/thumbnails/9.jpg)
9© Astex Therapeutics Limited
Why Bother?
• Quantifying and Managing Risk
• Hot Button for potential investors, collaborators, acquirers, IPO
• Risks of infringement• Cost of defending the suit • Injunction = loss of sunk cost, removal from market• Allowed to proceed but with royalty bearing license• Damages (potentially punitive if infringement wilful)
• Guide for internal scientific & business activities
• Policy should be to endeavour not knowingly to infringe valid third party rights

Small Company - Check Early, Check Often
• Credibility• Prepared for ‘Tricky’ Questions• Speed up Due Diligence• Influence scope of Warranties & Indemnities• Know risks for stacking royalties• Monitor third party IP & manage licensing strategy• Third parties FTO analysis• Opinions – Privilege• Drive licensing/business strategy
![Page 11: 2.30pm Jones Michelle - rsc.orgProf. Sir Tom Blundell, Harren Jhoti, Prof. Chris Abell, Roberto Solari • Internally generated pipeline of novel molecularly targeted oncology drugs](https://reader033.fdocuments.us/reader033/viewer/2022060719/607f9316605ab11ec1001cbc/html5/thumbnails/11.jpg)

Before embarking…
• Need to understand the key drivers right from the start • When you do it depends on the company and business strategy• You can’t do everything so what level of risk are you prepared to
accept• What can be done in budget and timescale• Short and Long term business objectives• Management understands what is being done and what is not being
done and risk in not doing it
Determines the requirements for FTO search and analysis
![Page 12: 2.30pm Jones Michelle - rsc.orgProf. Sir Tom Blundell, Harren Jhoti, Prof. Chris Abell, Roberto Solari • Internally generated pipeline of novel molecularly targeted oncology drugs](https://reader033.fdocuments.us/reader033/viewer/2022060719/607f9316605ab11ec1001cbc/html5/thumbnails/12.jpg)
12© Astex Therapeutics Limited
Check When
• Prior to embarking on research• Prior to foreign filing• Check at key transition points in development of a
product• Before key publications?• Periodically prior to introduction • Whenever parameters change• Monitor relevant patents, reassess & up date
![Page 13: 2.30pm Jones Michelle - rsc.orgProf. Sir Tom Blundell, Harren Jhoti, Prof. Chris Abell, Roberto Solari • Internally generated pipeline of novel molecularly targeted oncology drugs](https://reader033.fdocuments.us/reader033/viewer/2022060719/607f9316605ab11ec1001cbc/html5/thumbnails/13.jpg)

We all have the same search needs, but…
• Biotech Sector
• Search for own benefit plus benefit of others
• Due Diligence• Venture Capital & Debt• Out-licensing• In-licensing• Collaborations• External scrutiny
• Search earlier• No surprises during Due
Diligence!
• Pharmaceutical sector
• Search for own benefit
• Risk management• Internal projects• In-licensing• Pre-launch
• Search later?
![Page 14: 2.30pm Jones Michelle - rsc.orgProf. Sir Tom Blundell, Harren Jhoti, Prof. Chris Abell, Roberto Solari • Internally generated pipeline of novel molecularly targeted oncology drugs](https://reader033.fdocuments.us/reader033/viewer/2022060719/607f9316605ab11ec1001cbc/html5/thumbnails/14.jpg)
14© Astex Therapeutics Limited
FTO Due Diligence
• FTO Due diligence lists are fairly standardised
• For a Platform, full analysis of every step is required
• Research Program clearance needs to be better than many pharma’s would do for their internal research
• For Products (compounds/antibodies/nucleic acids) the timing of the clearance might be earlier than the corresponding in-house clearances
Third party is buying in solutions not problems

– Who do you need a license from?– Lack of certainty
• Keep good lab book records!!!
