**ANALYSIS REQUIREMENTS:**

Conduct a detailed analysis covering:

1. **Statutory Subject Matter (Section 2 of Patent Act)**
   - Assess if the invention constitutes "art, process, manufacture, or composition of matter"
   - Identify any potential excluded subject matter (abstract ideas, laws of nature, medical diagnostic/treatment methods)
   - Apply the purposive construction test from *Amazon.com* and *Choueifaty* decisions
   - Evaluate computer-implemented inventions under CIPO's 2023 guidance

2. **Novelty (Section 28.2)**
   - Analyze against anticipation by prior art (public knowledge, public use, sale, prior publication)
   - Consider grace periods under Section 28.2(1)(b) if applicable (12 months prior to filing date)
   - Flag any potential conflicting applications under Section 28.3
   - Assess enablement requirements for prior art (*Beloit Canada Ltd. v. Valmet Oy*)

3. **Inventive Step (Obviousness) - Section 28.3**
   - Apply the *Obvious to Try* test from *Sanofi-Synthelabo v. Apotex*
   - Identify the person skilled in the art (POSITA) and their common general knowledge
   - Analyze the state of the art through the *Windsurfing*/*Pozzoli* approach adapted for Canada
   - Evaluate if the invention was obvious to try in light of *Apotex Inc. v. Sanofi-Synthelabo Canada Inc.* and *Bristol-Myers Squibb Co. v. Canada (Attorney General)*
   - Consider secondary indicators (commercial success, long-felt need, unexpected results)

4. **Utility (Section 2)**
   - Assess if utility is demonstrated or soundly predicted (*Consolboard Inc. v. MacMillan Bloedel (Sask.) Ltd.*)
   - Check for "mere speculation" vs. actual utility (*Teva Canada Innovation*)
   - Evaluate sufficiency of disclosure (*Bristol-Myers Squibb Co. v. Canada (Attorney General)*)
   - Analyze the "promise of the patent" doctrine and post-*AstraZeneca* utility standards

5. **Double Patenting**
   - Flag potential "same invention" or "obviousness-type" double patenting issues
   - Consider terminal disclaimer strategies if applicable

6. **Sufficiency of Description (Section 27(3))**
   - Assess enablement requirements (*Prometheus Laboratories* standard)
   - Evaluate best mode requirements (if applicable to filing date)

**OUTPUT STRUCTURE:**

Provide your opinion in this format:

**PATENTABILITY SUMMARY**
- Overall probability of patentability (High/Medium/Low with percentage estimate)
- Key strengths (2-3 bullet points)
- Critical risks (2-3 bullet points)
- Recommended claim strategy (independent vs. dependent claims)

**DETAILED ANALYSIS**
[Section-by-section analysis with specific citations to relevant CIPO Manual of Patent Office Practice (MOPOP) sections, Patent Act provisions, and Federal Court/Supreme Court of Canada precedents]

**STRATEGIC RECOMMENDATIONS**
- Claim drafting suggestions to overcome anticipated CIPO objections
- Prior art citations to proactively address in the application
- Whether to file divisional applications (continuing applications under Section 73)
- Timing considerations (accelerated examination under Section 84 vs. normal track)
- PCT national phase entry considerations if applicable

**CONFIDENCE ASSESSMENT**
- State confidence level (High/Medium/Low) for each patentability criterion
- Note any information gaps that affect the opinion
- Suggest additional prior art searches if needed

Base your analysis on the Patent Act (R.S.C., 1985, c. P-4), Patent Rules (SOR/2019-251), CIPO Manual of Patent Office Practice (MOPOP) current edition, and relevant Federal Court/Supreme Court jurisprudence including *Whirlpool Corp. v. Camco Inc.*, *Sanofi-Synthelabo v. Apotex*, and *AstraZeneca Canada Inc. v. Apotex Inc.*
