推荐工作流
实用专利附图生成器 按素材准备、图纸生成、局部修改和提交前复核组织。
1
准备输入素材
使用足够清晰的产品照片、发明人草图、CAD 视图、方法权利要求或发明交底书，让 PatentFig AI 能理解结构关系。
2
生成专利图
生成黑白线条、视图关系和参考标号清晰的实用专利附图，并保持专利图常见的线条、版面和标号结构。
3
检查并导出
在布局、标号和文件格式稳定后，再进入检查和导出。
为什么这个场景需要专利专用工作流
优先保证专利图结构
不用每次从头开始
导出前先检查
Common mistakes in utility patent figure sets
Filing the same drawing set used for the design patent — utility figures need reference numerals and structural views, not appearance-only orthographics.
Submitting an overview figure with no companion detail, method, or cross-section figures.
Letting reference numerals drift between figures within the same application.
Treating broken lines as decorative shading instead of reserving them for hidden features.
实用专利附图生成器常见问题
实用专利附图生成器 是什么？
实用专利附图生成器 是 PatentFig AI 中把产品照片、发明人草图、CAD 视图、方法权利要求或发明交底书转换成黑白线条、视图关系和参考标号清晰的实用专利附图的工作流入口。
生成后还能继续修改吗？
可以。PatentFig AI 支持围绕布局、标号、箭头和图纸细节做多轮迭代。
它能替代专利代理人审查吗？
不能。PatentFig AI 用于加速制图和提交前检查，正式提交前仍需要律师或代理人复核。
How many figures does a typical utility patent need?
Five to twelve for a moderately complex invention. Simpler inventions can pass with three. The right number is whatever the spec and claims actually need to reference — not a target on its own.
Can I file utility patent drawings in color?
Under 37 CFR 1.84(a)(2) the USPTO accepts color drawings with a petition and additional fee, and only when color is necessary to disclose the invention. Default to black-and-white line art.
