Patent drawings must adhere to specific guidelines, including black-and-white line art, proper margins, consistent line thickness, and clear labeling. Each patent office (USPTO, EPO, PCT, etc.) has unique requirements, and we ensure compliance with all major offices.

You can submit sketches, hand-drawn images, CAD files, photos, 3D models, PDFs, Word documents, PowerPoint slides, and Visio files. Whether you have rough sketches or detailed 3D designs, we can convert them into high-quality patent drawings.

We sign NDAs (Non-Disclosure Agreements) upon request and follow strict confidentiality protocols to ensure your intellectual property remains secure. Your files and invention details are handled with complete discretion.

Our pricing is $20 per sheet for utility patent drawings and $30 per sheet for design patent drawings. The final cost depends on the complexity and number of views required.

Typically, we deliver utility patent drawings within 1-2 days and design patent drawings within 2-3 days. Urgent requests can be accommodated with expedited delivery.

Utility patent drawings illustrate the functional aspects of an invention, while design patent drawings focus on the appearance and ornamental design. Design patents require more precise shading and contouring.

Absolutely! We can redraw, modify, or enhance existing patent drawings to meet USPTO, EPO, UKIPO, and other patent office standards. We also convert hand-drawn sketches or low-quality images into professional, patent-compliant illustrations.
