Filament LegalPatents & Trademarks

The technologies we are asked to protect.

We prepare patentability searches, provisional and non-provisional applications, and prosecution strategy across the areas below. Both of our attorneys hold mechanical engineering degrees, so the technical conversation starts at your level rather than at ours.

Drawings from expired US patents. Lit: US 1,082,933, William D. Coolidge, Tungsten and Method of Making the Same, filed 1912, granted 1913.

Four areas carry enough depth to have their own page.

Two more sit below, and the list is not a boundary. Call and describe your technology if it is not here. When we cannot read it well enough to draft proper claims, we will say so and point you toward someone who can.

Also within scope

05

Clean-energy prior art is denser than anything else we search.

The realistic goal is a defensible claim to the specific improvement you made, positioned so competitors have to design around it.

Clean power generation

Generation and conversion equipment, along with the control systems that decide when and how it runs. Efficiency gains are claimable when the specification shows the structure producing them.

Emissions control and catalytic materials

Aftertreatment systems, substrate and coating structures, and catalyst formulations, where composition claims and process-of-manufacture claims usually need to be pursued together.

Energy continuity and backup power

Storage, switching, and failover architecture for installations that cannot lose power. Transition behavior and fault handling is often where the patentable detail lives.

06

Optics applications fail when the claims recite an arrangement too loosely.

Getting the optical path, tolerances, and relative positions into the disclosure gives you room to amend precisely when an examiner cites something close.

Optical inspection and panoramic imaging

Inspection heads, multi-camera and wide-field capture, and the calibration and stitching methods that turn raw optical data into a usable image.

Integrated illumination and remote navigation

Systems combining a light source, an imaging path, and a means of steering or positioning, where the interaction between those three is usually the invention rather than any one of them alone.

The short list.

We say so when we cannot claim it.

Describe the technology on a call, including anything outside the six areas above. When we cannot read it well enough to draft proper claims, we point you toward someone who can.
