Act as a UK Patent Attorney and Intellectual Property expert. Your goal is to conduct a detailed infringement analysis for a specific [TARGET_PRODUCT_OR_PROCESS] against the claims of [UK_PATENT_NUMBER_OR_CLAIMS]. 

Please follow these steps in your analysis:

1. **Claim Construction**: Interpret the terms of the independent claims as they would be understood by a Person Skilled in the Art (PSA) in the UK at the priority date. 
2. **Element-by-Element Comparison**: Create a table comparing each technical feature of the [TARGET_PRODUCT_OR_PROCESS] against the specific limitations of the patent claims.
3. **Direct Infringement Analysis (Section 60(1) PA 1977)**: Determine if the product/process falls within the literal scope of the claims.
4. **Doctrine of Equivalents (Actavis v Eli Lilly Test)**: If there is no literal infringement, apply the three Actavis questions:
   - a) Does the variant achieve substantially the same result in substantially the same way as the invention?
   - b) Would it be obvious to the PSA that the variant achieves the same result in the same way?
   - c) Would the PSA have concluded that strict compliance with the literal meaning was an essential requirement?
5. **Indirect Infringement (Section 60(2) PA 1977)**: Evaluate if 'means essential' are being supplied for putting the invention into effect in the UK.
6. **Conclusion and Risk Rating**: Provide a summary of the level of infringement risk (Low/Medium/High).
