Highlighting
Feature

A full end-to-end project I led solo — research, design, and dev handoff — during a period of significant organisational change.

My role
Senior UX Designer, acting lead

Build in progress · Alpha complete

01 Context

I didn't plan to run this alone. But I did.

During this project Clarivate went through significant redundancies. The PM was let go. The delivery manager was let go. I stepped up, doing the research, writing the first draft of user stories, managing stakeholder alignment, and making product calls alongside Matt Weber, our PM Director.

It wasn't the plan. It was just what the project needed.

Expert users don't forgive bad tools

Patent attorneys, IP strategists, professional searchers. People with decades of experience and very precise mental models. They don't change workflows for novelty. They change when something is measurably better.

Two audiences, one shot

Power users had built workarounds. Some had migrated parts of their workflow to competitor tools. New users expected speed and intelligence out of the box. Both groups had to be served.

02 The problem

Highlighting is not a nice-to-have. It's how patent analysis works.

Reading a patent isn't like reading an article. A single document can run to hundreds of pages of dense technical and legal language. Analysts aren't reading for pleasure. They're hunting for specific concepts, under time pressure, often across dozens of documents in a single session.

Highlighting is the primary navigation tool for that hunt. Without it, or with a version too basic to be useful, the work becomes slower and riskier. A missed term in a prior art search isn't an inconvenience. It can invalidate a patent claim.

What Derwent had

One word per colour. No concept groups. No synonyms. No way to track "battery", "Li-ion" and "energy storage cell" together. A tool so basic that experienced users had stopped using it.

What competitors offered

Richer highlighting, multi-term search, better document navigation. Users knew the gap existed. They were actively filling it with third-party tools and competitor products.

"I am waiting for this feature for many, many years."
Dr. Ulrich, IP analyst. Said unprompted, at the start of his session.
"I turn off the highlighting in Derwent. I use Multi Find."
Mrinal Bhaskar. He had abandoned the feature entirely and built his own workaround.
03 Research

18 sessions. One researcher. Zero hesitation to change course.

I ran every session myself. Professional searchers, IP analysts, attorneys, and senior internal stakeholders including a Patent Search Principal Lead and a Director of Patent Operations. We made a deliberate call to iterate fast. When something came up consistently across sessions, we fixed it immediately rather than waiting for the study to end.

failure rate after icon fix

The clearest example: icon-only buttons were invisible to users. After 8 consecutive failures I switched to labelled buttons mid-study. Failure rate dropped to zero.

Before — sessions 1 to 8

Icons only. 8 out of 8 participants failed to find the feature unprompted. Common response: "I didn't realise that was clickable."

After — sessions 9 to 18

Labelled buttons. 0 out of 5 failed. Discovery was immediate and unprompted.

Must haveMini Map — every session, every participant. Time savings from 1–2 min/doc up to 50% for heavy users.
Must haveMultiple words per colour. One colour = one concept = all its synonyms. The number one pain point in the existing tool.
Must haveQuery term auto-load. Terms pre-load when a patent opens. Every single participant wanted this.
Must haveTemplates. Save and reuse concept groups across patent families.
Should haveProximity highlighting. High value once found, but too hidden. Users wanted 3 or more word proximity.
"The most useful is the map. Absolutely, definitely the most useful."
Brian Larner, professional patent searcher.
04 The design

A patent document, compressed into a navigation tool.

The Mini Map lives in the right panel. Always visible, always the exact height of the document viewer. Colour marks show where every concept group appears. Click any mark, jump to that exact line. Scroll the document, the indicator moves. Always in sync.

02
Three ways to read the same data
List gives a hit count per concept group. Matrix breaks it down by document section. Mini Map shows it spatially — position and density at a glance. Users switch between them without losing context.

Adding words — your concepts, your synonyms
Each colour group holds multiple synonyms. Type them in, press Enter. The system tracks all of them together — one concept, one colour, across the entire document.

AI finds what you didn't think to search for
The AI panel surfaces related terms automatically. "Siloxane" suggests "silicone". "Skin" suggests "dermis". Users pick what's relevant. Nothing is added without their say.

Templates — one click, full research setup
Save concept groups as templates. Reuse them across an entire patent family. Every colour group, every synonym, every operator — loaded instantly.

05 AI in my workflow

Faster and more thorough. Not on autopilot.

I used Claude to pressure-test spec logic, catch inconsistencies across documents, and draft sections of the handoff. Running this solo means no second designer reviews your calculations. AI helped close that gap.

I checked everything. Every number. Every assumption. The design decisions, the research synthesis, the prioritisation — that was mine.

Knowing how to use AI consciously, with proper oversight, is itself a skill. One I've deliberately built.

Transparent AI use

Where AI helped most:

  • Pressure-testing the Mini Map height and row distribution calculations
  • Catching inconsistencies between the spec, responsive rules, and Figma guide
  • Drafting and structuring the developer handoff documentation
  • Acting as a second pair of eyes when no second designer was available
06 Impact

Three sources. Kept separate on purpose.

The numbers below come from three different places and mean three different things. Mixing them would make the story dishonest.

① Before Product baseline — before this project Pendo · 114,198 users

Record View is the strongest retention driver in the product. Users who engage with it in the first 2 days are retained at nearly double the rate of those who don't. The highlighting feature lives inside Record View. A broken highlighting experience was actively undermining the stickiest part of the product.

Multiple participants had already moved parts of their workflow to competitor tools specifically because of the highlighting limitation. This feature is a direct win-back opportunity.
