Ash Cunningham

Expert witness · User experience & interface design

What did the interface actually ask the user to do?

I help counsel answer that question with evidence. Twenty-five years designing consumer and enterprise products at Apple, LinkedIn, Looker, NerdWallet and more than forty startups, applied to disputes over consent, disclosure, usability and design infringement.

Areas of opinion

Where design decisions become legal questions

Each area below draws on work I have done as a practitioner, not only as a reviewer. I can tell the court how teams build these flows, what the industry knew at the time, and what a reasonable alternative would have looked like.

Was consent clear and conspicuous?

Dark patterns & consumer protection

Pre-checked boxes, drip pricing, confirmshaming, obstructed cancellation and negative-option subscriptions, evaluated against FTC guidance, ROSCA and state auto-renewal laws.

Would a reasonable user have seen it?

Disclosure, terms & online contract formation

Sign-in-wrap and clickwrap presentation, placement and visual weight of notices, and whether the design gave users a real opportunity to review terms.

Is the similarity functional or protectable?

Design patents, trade dress & UI copying

Comparative analysis of screens, icons and flows. Separating conventions every product shares from distinctive choices, with design-history context from the App Store era forward.

Did the product meet the standard of care?

Software delivery & usability disputes

Enterprise implementations, agency and vendor engagements, and products that failed in use. Assessment of research practice, specifications, handoff and what competent delivery requires.

Could a person with a disability use it?

Digital accessibility

Website and app accessibility claims measured against WCAG 2.x, with task-based evaluation of the barriers a specific plaintiff would have encountered.

How was the user steered?

Financial & data-privacy interfaces

Rate and product comparison displays, cookie and tracking consent, and permission prompts, informed by product work in personal finance, data analytics and telecom.

Qualifications

Practitioner first

I have spent a career on the other side of these screens, making the trade-offs between conversion, clarity and compliance that later end up in discovery.

I am a systems designer and design lead with roughly 25 years in product and UX design, from consumer marketplaces to enterprise operations tools. I currently lead UX for internal agent and enterprise tooling at a national telecom provider and run an independent studio, AE Design Studio. I hold a BFA from CalArts.

That experience lets me explain to a judge or jury how product teams actually decide what goes on a screen, and what alternatives were available at the time.

Method

Opinions built to survive Daubert

Every opinion rests on a documented, repeatable method that another qualified expert could follow and test.

Reconstruction as served

Rebuilding the interface the user actually saw on the relevant date, device and screen size, from production files, design archives, version history and web archives.

Heuristic & standards review

Structured evaluation against published usability heuristics, platform guidelines, WCAG and regulatory guidance, with each finding tied to a criterion.

Comparative analysis

Side-by-side review against competitors and industry practice of the period, to show what was customary and what reasonable alternatives existed.

Design-record review

Reading specs, tickets, A/B test results and design files to show what the team intended and what it measured.

User testing

Where the case warrants it, task-based studies with representative participants to test whether users noticed and understood a disclosure.

Annotated exhibits

Clear, accurate demonstratives that let a judge or jury see the issue on the screen, as in the example above.
