  • Technology alternatives
Boolean Queries: Create multiple search queries combining:
(keyword1 OR synonym1) AND (keyword2 OR synonym2) AND (keyword3 OR synonym3)
Generate at least 5-10 different query combinations.
CPC/IPC Classifications:
  • Identify primary classification
  • Find secondary classifications
  • Use classification hierarchy
Run Tool (if available):
bash
cd tools && python prior-art-search.py ../patents/drafts/[invention-file].md
Document Strategy: Create
patents/analysis/[invention-name]-search-strategy.md
:
  • All search queries

  • Databases to search
  • Search rationale
关键词提取:
  • 核心技术术语
  • 同义词及变体
  • 相关概念
  • 技术替代方案
布尔查询: 创建多个组合搜索查询,格式如下:
(keyword1 OR synonym1) AND (keyword2 OR synonym2) AND (keyword3 OR synonym3)
生成至少5-10种不同的查询组合。
CPC/IPC分类:
  • 确定主分类号
  • 查找次分类号
  • 利用分类层级
运行工具(如有):
bash
cd tools && python prior-art-search.py ../patents/drafts/[invention-file].md
记录策略: 创建文件
patents/analysis/[invention-name]-search-strategy.md
,包含:

Step 4: Initial Reference Screening

步骤4:参考文献初筛

For each reference found:
  • Read title and abstract
  • Assess relevance (high/medium/low)
  • Note publication date
  • Check if enabling
  • Determine if potentially anticipating
High Relevance: Has most/all key features Medium Relevance: Has some key features Low Relevance: Related but missing critical features
Focus on high-relevance references (typically 5-15 references).
针对找到的每份参考文献:
  • 阅读标题和摘要
  • 评估相关性(高/中/低)
  • 记录出版日期
  • 检查是否具备实施可能性
  • 判断是否可能构成抵触
高相关性:包含大部分/全部关键特征 中相关性:包含部分关键特征 低相关性:相关但缺少核心特征
重点关注高相关性参考文献(通常为5-15条)。

Step 5: Detailed Analysis

步骤5:详细分析

For each high-relevance reference:
Read Thoroughly:
  • Full patent/publication
  • All claims (for patents)
  • Figures and examples
  • Background section
Extract Key Information:
  • Patent/publication number
  • Title
  • Inventors/authors
  • Publication date
  • Priority date
  • Key features disclosed
  • Relevant figures
  • Relevant claims (if patent)
针对每份高相关性参考文献:
全面阅读:
  • 完整专利/出版物
  • 所有权利要求(针对专利)
  • 附图和实施例
  • 背景技术部分
提取关键信息:
  • 专利/出版物编号
  • 标题

  • 出版日期
  • 优先权日
  • 公开的关键特征
  • 相关附图
  • 相关权利要求(针对专利)

For each high-relevance reference, create element-by-element comparison.
Use template structure:
markdown
undefined
针对每份高相关性参考文献,创建逐要素对比表。
使用以下模板结构:
markdown
undefined

Reference: [Patent Number] - [Title]

参考文献: [专利编号] - [标题]

Publication Date: [Date] Relevance: High/Medium/Low
出版日期: [日期] 相关性: 高/中/低

Analysis

分析

Disclosed Elements: [List] Missing Elements: [List] Differences: [Describe key differences]

Create comprehensive claim charts for at least top 3-5 references.
已披露要素: [列表] 缺失要素: [列表] 差异点: [描述核心差异]

至少为前3-5份参考文献创建完整的权利要求对比表。

Step 7: Anticipation Analysis (§ 102)

步骤7:抵触分析(§ 102)

For each reference:
Single Reference Test:
  • Does it disclose ALL claim elements?
  • Is disclosure enabling?
  • Is publication date before priority date?
Conclusion Per Reference:

  • Potentially Anticipates: All elements arguably present
  • Does Not Anticipate: Missing elements
Overall § 102 Assessment:
  • Is invention novel?
  • Which claim elements are novel?
  • What distinguishes invention?
针对每份参考文献:
单一参考文献测试:
  • 是否披露了所有权利要求要素?
  • 披露内容是否具备实施可能性?
  • 出版日期是否早于优先权日?
每份参考文献的结论:
  • 构成抵触: 所有要素齐全、具备实施可能性、日期符合要求
  • 可能构成抵触: 所有要素可被认为已披露
  • 不构成抵触: 缺少要素
整体§ 102评估:
  • 发明是否具备新颖性?
  • 哪些权利要求要素具备新颖性?
  • 发明的独特之处是什么?

Step 8: Obviousness Analysis (§ 103)

步骤8:显而易见性分析(§ 103)

Combination Analysis:
Test reasonable combinations:
  1. Reference A + Reference B
  2. Reference A + Reference C
  3. Reference B + Reference C
  4. etc.
For Each Combination:
Graham Factors:

  2. Differences: What's missing from combination?
  3. Skill level: How sophisticated is the art?
  4. Secondary considerations:
    • Unexpected results?
    • Commercial success?
    • Long-felt need?
    • Failure of others?
Motivation to Combine:
  • Would skilled person be motivated to combine?
  • Is motivation explicit or implicit?
  • Any teaching away from combination?
  • Is combination obvious to try?
KSR Factors:
  • Obvious to try?
  • Predictable variation?
  • Known technique to known device?
  • Simple substitution?
Conclusion Per Combination:
  • Likely Obvious: Clear motivation, predictable result
  • Potentially Obvious: Arguable motivation
  • Not Obvious: No motivation or unpredictable result
Overall § 103 Assessment:
  • Is invention non-obvious?
  • Strongest combination against claims?
  • What makes it inventive?
组合分析:
测试合理的组合方式:
  1. 参考文献A + 参考文献B
  2. 参考文献A + 参考文献C
  3. 参考文献B + 参考文献C
  4. 其他组合
针对每种组合:
Graham因素:
  1. 现有技术范围: 参考文献传授了什么内容?
  2. 差异点: 组合内容中缺少什么?
  3. 技术水平: 该领域的技术成熟度如何?
  4. 次要考量因素:
    • 是否有意外效果?
    • 商业成功情况?
    • 是否存在长期未满足的需求?
    • 他人是否尝试失败?
组合动机:
  • 本领域技术人员是否有动机进行组合?
  • 动机是明确的还是隐含的?
  • 是否有文献反对该组合?
  • 该组合是否属于显而易见的尝试?
KSR因素:
  • 是否属于显而易见的尝试?
  • 是否是可预测的变体?
  • 是否为已知技术应用于已知装置?
  • 是否为简单替换?
每种组合的结论:
  • 可能具备显而易见性: 明确的动机、可预测的结果
  • 可能具备显而易见性: 动机存在争议
  • 不具备显而易见性: 无动机或结果不可预测
整体§ 103评估:
  • 发明是否具备非显而易见性?
  • 针对权利要求的最有力组合是什么?
  • 发明的创造性体现在哪里?
