Technical drawings that show exactly how your invention works.
Examiners read the drawings alongside the claims, and every claimed feature must appear in them. Our illustrators turn sketches, photos and CAD files into formal utility patent drawings, with the views, numerals and shading each office requires, usually within one to two business days.
- Every view you need: perspective, exploded, sectional, schematic
- Matched to your claims, with reference numerals that track the text
- Compliant with USPTO, EPO, PCT and IP India rules

Drawings that work alongside your claims, not just next to them.
Utility patent drawings show how an invention is built, how it works or how a method is carried out. Most offices require drawings wherever they are needed to understand the invention, and every feature recited in the claims must be shown. Reference numerals tie each part in the figures to the description.
Well-prepared drawings make examination faster, can support amendments later, and give licensees, experts and courts a clear picture of the invention. Poor drawings lead to objections and, in the worst case, to features that cannot be claimed.

Eight kinds of figure, one consistent set.
Most applications combine several kinds of figure. We choose the views that show each claimed feature most clearly, and keep numbering and style consistent across the set.
Illustrators who understand your field.
Each technology has its own conventions. Our illustrators specialise, so a circuit looks like a circuit and a chemical scheme follows chemical convention.
Mechanical
Engines, tools, machines, vehicle parts and mechanisms, where structure and movement matter.
- Perspective and exploded assemblies

- Moving parts in alternative positions
- Detail views of key features
- Consistent part numbering across figures
- Prepared from CAD, photos or sketches
Electrical and electronics
Circuits, semiconductors, sensors and power systems.
- Circuit schematics and wiring diagrams
- Block diagrams of system architecture
- Chip layouts and cross-sections
- Timing diagrams and waveforms
- Signal flow and interfaces
- Standard symbols used consistently
Software and AI
Algorithms, platforms and user interfaces, where method steps carry the claims.
- Method flowcharts with step numbers
- System and network architecture
- Neural network and data pipeline diagrams

- Mechanism and actuation sequences
- Electronics and control diagrams
- Detail views of contact surfaces
- Consistent with regulatory documentation
Consumer products
Appliances, wearables, packaging and personal care devices.
- Perspective and exploded views
- Internal mechanisms shown in section
- Use and alternative positions
- Packaging and closure details
- Electronics where relevant
- Coordinated with design drawings if filed
Nine rules every set must follow.
Each office sets out how drawings must look. These are the points examiners check most often, and we check every one before delivery.
Line quality
Black, uniform, well-defined lines that reproduce clearly.
Sheet size and margins
A4 or letter sheets with each office’s margins.
Figure numbering
Figures numbered consecutively, with sheet numbers.
Reference numerals
Numerals placed clearly, matching the description exactly.
Shading
Line shading for curved and flat surfaces, used sparingly.
Scale
Large enough to read when reduced, consistent within a figure.
Text in drawings
Kept to essential words such as labels in flowcharts.
Colour and photographs
Black and white by default; colour only where allowed.
Section hatching
Cut surfaces hatched, with section lines marked.

Request a drawings quote01What are utility patent drawings?
Figures that show how an invention is built, how it works or how a method is performed. They are filed with the specification and claims and use reference numerals to link each part to the description.
02What is the purpose of utility patent drawings?
To help the examiner and later readers understand the invention, and to show every feature recited in the claims. They can also support amendments during prosecution and serve as clear evidence in licensing and disputes.
03How are utility drawings different from design drawings?
Utility drawings explain structure and function, with reference numerals and views chosen to show how the invention works. Design drawings define the appearance of a product and are the main part of a design application.
04Which views should my application include?
It depends on the invention. Mechanical inventions usually need perspective, exploded and sectional views; electronics need schematics and block diagrams; software and methods need flowcharts. We recommend the set for your claims.
05Can you work from rough sketches?
Yes. Hand sketches, photos of a prototype, CAD files or a draft specification are all fine starting points.
06How long does it take?
Typically one to two business days, depending on the number and complexity of figures. Rush delivery is available for urgent filings.
07What formats do you deliver?
PDF and TIFF for filing as standard, with editable source files and other formats available on request.
From sketch to formal drawings in days.
