Patent Drawing in Austin.

Patent drawing services Austin companies need have to clear two very different bars. The first is a formalities review at the USPTO, where a draftsperson checks margins, line weight and reference characters against 37 CFR 1.84. The second comes years later, when the same figure is blown up on a screen in the Western District of Texas and a jury is asked what it shows. Austin files heavily in semiconductors, software and hardware, and all three produce figures — layer stacks, flowcharts, exploded assemblies — that fail in characteristic ways. PerspireIP drafts for both audiences at once.

Where patent drawing services Austin filers actually file

There is no patent office in Austin. The USPTO’s Texas Regional Office sits in Dallas, roughly 200 miles north, and even that office does not take over-the-counter filings the way applicants sometimes assume — it houses examiners, administrative patent judges and outreach staff. Every Austin application is filed electronically through Patent Center, which means your drawings are judged as uploaded files, not as paper.

That has a practical consequence Austin filers underestimate. The figure that looks crisp in your CAD viewer is scanned, reduced and reproduced in black and white for publication. Hairline strokes, 6-point reference numerals and grey gradients that read perfectly at 400% zoom disappear at publication scale, and the objection arrives months later as a Notice of Draftsperson’s Patent Drawing Review attached to a first action.

The other route Austin companies use heavily is the PCT, filed with the USPTO as receiving office, followed by national phase in Europe, China, Korea, Japan and Taiwan — the markets where this city’s semiconductor and hardware customers sit. Each of those offices applies its own presentation rules to the same drawing set, which is why a single figure package should be built to the strictest common denominator from the start.

37 CFR 1.84: the rules that actually generate objections

The federal drawing standard is 37 CFR 1.84, and only a handful of its subsections account for most deficiency notices:

• Sheet size and margins (1.84(f), (g)). Sheets are either 21.0 x 29.7 cm (A4) or 21.6 x 27.9 cm (8 1/2 x 11 in), with a top and left margin of 2.5 cm, a right margin of 1.5 cm and a bottom margin of 1.0 cm. Nothing may sit in the margin.
• Line quality (1.84(l)). Every line, number and letter must be durable, clean, black, sufficiently dense and dark, and uniformly thick and well-defined. Anti-aliased CAD exports and variable-weight strokes are the recurring failure.
• Sectional hatching (1.84(h)(3)). Hatching must be oblique parallel lines spaced far enough apart to be distinguished without difficulty. Dense hatching fills to solid black on reduction.
• Reference characters (1.84(p)). Numerals and letters must be at least 0.32 cm (1/8 in) high, must not cross or mingle with the lines, and every character in a figure must appear in the description.
• Shading (1.84(m)). Solid black shading areas are not permitted except to represent bar graphs or colour — a rule that runs the opposite way for design drawings under 37 CFR 1.152.

Design filings follow a different path. Under 37 CFR 1.152 the drawing is the claim, and the split between solid and broken lines decides scope. For Austin’s consumer-hardware and app companies that is often the more consequential filing.

Semiconductor figures: the Austin-specific problem

Austin is a fab town, and fab patents draw badly. A device claim lives in a cross-section of a layer stack where a dozen films differ by tens of nanometres, and the draftsperson has to distinguish them using nothing but oblique parallel hatching at a spacing that survives reduction. Get the spacing wrong and two adjacent dielectric layers reproduce as one black band — which is both a formalities objection and, later, an ambiguity an opponent will exploit.

The recurring issues in the semiconductor sets we redraw are consistent:

• Hatching patterns reused for different materials across figures, so the same fill means silicon in Fig. 2 and oxide in Fig. 5.
• Cross-sections with no section line shown on the plan view, leaving the cut plane undefined.
• Process-flow figures that carry so much text they read as a specification page rather than a drawing.
• Reference numerals stacked so densely they touch the lines they label, contrary to 1.84(p)(3).

Not to scale is not a defence here. Drawings need not be to scale, but they must be consistent and legible, and a stack that is unreadable after reduction has disclosed nothing.

The Western District of Texas: Austin, Waco and what changed in 2022

Austin sits in the Austin Division of the U.S. District Court for the Western District of Texas, and the WDTX became, for a period around 2020 and 2021, the single busiest patent venue in the country. Almost all of that volume ran through the Waco Division and Judge Alan Albright, roughly 100 miles north of Austin.

That is no longer how the district works, and filers relying on stale advice get this wrong. In July 2022 the district issued an order directing that patent cases filed in the Waco Division be randomly assigned among a pool of district judges across the WDTX rather than going automatically to a single judge. Filing volume redistributed sharply afterwards. An Austin defendant today may draw a judge in Austin, El Paso, San Antonio or Waco.

What has not changed is the evidentiary role of your figures. In a district-court case the drawings are claim-construction material: the specification’s figures inform what a claim term means, and a figure that contradicts the written description hands the other side an argument. Litigation-grade redrawing — clean, labelled, consistent across the family — is far cheaper before a complaint than after one.

Why an Austin address creates venue

Austin’s concentration of engineering offices is not just an economic fact; it is a venue fact. In TC Heartland LLC v. Kraft Foods Group Brands LLC, 581 U.S. 258 (2017), the Supreme Court held that for patent venue under 28 U.S.C. § 1400(b) a domestic corporation resides only in its state of incorporation. That narrowed venue dramatically and pushed the analysis onto the statute’s second prong: a regular and established place of business where acts of infringement occurred.

The Federal Circuit then supplied the test in In re Cray Inc., 871 F.3d 1355 (Fed. Cir. 2017): the place must be a physical place in the district, it must be regular and established, and it must be the defendant’s own place rather than an employee’s. A staffed Austin engineering campus satisfies that comfortably. That is precisely why so many technology companies with Delaware incorporation still find themselves litigating in Central Texas.

For an IP team the practical read is simple: if you maintain an Austin facility, assume your patents may be litigated here, and build the figure set accordingly.

PTAB proceedings and drawings that carry a petition

Parallel to district-court litigation sits the Patent Trial and Appeal Board. An inter partes review petition is a document built on figures — annotated prior-art drawings mapped element by element against the challenged claims. Petitioners routinely colour-code and annotate prior-art figures; patent owners routinely attack those annotations as unsupported.

Two drawing-side points matter. First, a published drawing is prior art for everything it reasonably discloses to a skilled person, whether or not the text discusses it, so your own back-catalogue of figures is part of the art others will use. Second, annotated versions of a figure must be identifiable as annotations, not presented as the original. Austin’s semiconductor and software portfolios are heavily represented in IPR practice, and the quality of the original figure set determines how much annotation work is even possible.

The industries behind Austin filing volume

Central Texas patent demand is concentrated in three clusters, and each produces a distinct drawing profile.

• Semiconductors. Samsung Austin Semiconductor has operated fabs in the city for decades and is building a large new facility at Taylor, about 30 miles northeast, announced in November 2021. NXP runs Austin fabs; AMD, Applied Materials, Infineon and Silicon Labs, which is headquartered here, all maintain significant Austin engineering. These files need cross-sections, hatching discipline and process-flow figures.
• Software and systems. Dell is headquartered in nearby Round Rock, Apple runs one of its largest campuses outside Cupertino in North Austin, and Tesla’s Gigafactory Texas and corporate base sit east of the city. These files need flowcharts, block diagrams and, increasingly, GUI design patents where broken-line practice governs scope.
• University and public research. The University of Texas at Austin, its Cockrell School of Engineering and the Texas Advanced Computing Center generate a steady stream of licensed and spun-out technology, and Army Futures Command has been headquartered in the city since 2018.

The common thread is that Austin filers are usually building international families from day one, not US-only filings.

Taking Austin figures to the EPO and through the PCT

When an Austin family goes abroad, the drawing rules change underneath it. Two points are current and frequently misstated.

The EPO. Rule 46 EPC, headed “Form of the drawings,” was deleted with effect from 1 February 2023. The form requirements moved into a Decision of the President of the EPO so they can be revised without amending the Implementing Regulations. Any checklist or vendor still citing Rule 46 EPC as live law is out of date. Separately, since 1 October 2025 the EPO accepts drawings filed electronically in colour or greyscale, provided they are contrast-rich and clearly reproducible; the description, claims and abstract remain black and white.

The PCT. The PCT was not changed to match. Rule 11.13 still requires drawings in durable, black, sufficiently dense and dark, uniformly thick and well-defined lines and strokes without colourings. A colour figure that the EPO will now accept on a direct European filing is still non-compliant in an international application, so a family that runs US → PCT → EP needs the monochrome set prepared regardless.

The workable answer for an Austin filer is a single monochrome master built to 37 CFR 1.84 and PCT Rule 11.13, with colour or greyscale variants produced only where a designated office both permits and benefits from them.

How PerspireIP delivers patent drawing services Austin teams can file

We work from whatever you have — a provisional, a disclosure memo, CAD geometry, die photographs, screen captures or a competitor’s published figures for a litigation exhibit. What comes back is a numbered figure set with a reference-numeral table reconciled against the description, formatted for the office you are filing in.

• Utility figures to 37 CFR 1.84, including sectional views with compliant oblique hatching.
• Design figures to 37 CFR 1.152, with the solid and broken line split set deliberately to the claim scope you want.
• GUI and screen-display sets for software and consumer filings.
• PCT-ready monochrome masters and EPO variants prepared to the current Decision of the President.
• Litigation and IPR redraws, including annotated prior-art figures clearly marked as annotations.
• Responses to Notices of Draftsperson’s Patent Drawing Review, with corrected sheets prepared for filing.

Turnaround is normally a few business days for a standard utility set, with same-week handling where a bar date or a filing window is driving the schedule.
