Trusted by IP firms globally
Your AI associate for IP business development.
Lexi is built around live patent and trademark signals, in a CRM that updates itself. She prospects, drafts outreach, preps meetings, and keeps your pipeline current. Every outbound action queues for your approval. From first touch to signed engagement, your firm runs faster.
She acts, not just writes.
Drafts outreach. Preps meetings. Updates deals. Triggers automations. Scans business cards. Lexi works inside LeadLex 24/7 — and queues every outbound message for your approval before anything goes out.
She lives where you already work.
Teams, WhatsApp, Slack, or email. “Prep me for my 2pm with Baker.” “Follow up with everyone from INTA.” No app to install. Lexi shows up in every channel your firm already uses.
She gets sharper every week.
Week one: Lexi learns your pipeline stages and partner channel preferences. Month one: most partners say her drafts need only light edits. Quarter one: she’s flagging contacts that need nurture before you ask.
Lexi sees what your CRM can’t.
IP BD runs on signals generic CRMs never ingest. Lexi reads them at the source — patent offices, trademark registries, court dockets, opposition divisions — and turns each one into a tracked BD trigger queued for your approval.
Patent filings
EPO, USPTO, WIPO PCT, JPO, CNIPA. New filings flagged within hours of publication, filtered to your technology areas.
Trademark filings & renewals
EUIPO, USPTO, WIPO Madrid, and 30+ national registers. Renewal calendars, conflicting applications, and expansion intent from brands without local counsel.
Prosecution milestones
Office actions, response deadlines, allowance and grant events tracked on every matter where you have a relationship.
Opposition deadlines
EPO opposition divisions and EUIPO opposition windows. Lexi flags the conflict the day the window opens.
IP-counsel movement
In-house IP managers and heads of legal changing companies. The relationship trigger generic CRMs never see.
The data layer compounds with use. No horizontal player will rebuild it for a market they consider too small — which is why we’ll still be the IP-native choice in five years.
No new app. No new login. No CRM to keep current.
Most CRMs die because partners won’t log in. Lexi lives in the channels lawyers already use — text her, forward an email, drop a voice note. The CRM stays current in the background.
The more partners talk to Lexi in-channel, the richer the Firm Memory Graph — and the more her drafts sound like the partner, not like a bot.
WhatsApp
Text Lexi. Forward business cards. Drop a voice note from a conference floor.
Microsoft Teams
Native bot. Daily briefings before your 9am, queued drafts in your DMs.
Slack
Channel mentions, slash commands, scheduled digests, partner-by-partner queues.
Email
Forward anything to Lexi. She extracts contacts, logs the thread, drafts the follow-up.
A CRM that updates itself — so partners actually use it.
Lexi lives in Teams, WhatsApp, email, and Slack. Text her, forward an email, or drop a voice note. We don’t expect you to learn a new tool — your CRM stays current in the background.

Set rules once, Lexi repeats forever
“Flag every new filing from Siemens.” “Follow up with any contact I haven’t spoken to in 60 days.” Set automations once and Lexi runs them continuously.
Network
Every contact auto-enriched from patent offices, courts, and registries. One view for activity, deals, notes, emails, and meetings.
Prospector
210M+ contacts. Search by practice area, jurisdiction, or company. Lexi scores matches and drafts your outreach.
Pipeline & Deals
Three pipelines — Development, Acquisition, Retention. Lexi flags stale deals and drafts re-engagement automatically.
Events & Conferences
Attendee research, meeting prep, business card scanning, and post-event follow-ups — all in one workflow.
INTA season, without the chaos.
The IP circuit produces stacks of business cards that never become tracked relationships. Lexi runs the loop end to end — pre-event prep, on-site capture, post-event follow-up — without you ever opening a CRM.
- Stage 1
Before
Lexi finds the right events from your calendar, identifies who’s attending, cross-references your contacts, and prepares per-attendee briefing notes.
- Stage 2
On-site
Scan a business card with your phone. Lexi enriches the contact, links public IP filings, and queues a follow-up draft before you leave the venue.
- Stage 3
After
Bulk-personalised follow-ups in your voice, queued for your approval. Track event ROI by mandates won, not by cards collected.
The AI never sends anything you didn’t approve.
Every outbound action runs through a delegation ladder. Partners start fully supervised and grant Lexi more autonomy as trust builds — not the other way around. This is how we cross the partner-adoption chasm that killed every prior legal CRM.
- Step 1
Supervised
Every action shows up in your approval queue. Lexi drafts, you read, you send. Start here.
- Step 2
Co-pilot
Lexi drafts and queues; you batch-approve in seconds. Most partners settle here within a month.
- Step 3
Authorized
Lexi acts on a whitelist of low-risk actions (e.g., warm follow-ups) without approval. You retain audit and undo.
- Step 4
Blocked
Any contact, deal, or action can be blocked from Lexi entirely. Privileged matters stay off-limits.
Plus full audit trail, 24-hour undo on every sent action, and per-contact / per-matter blocks so privileged work stays off Lexi’s desk.
Built for patent, trademark, and IP-litigation practices.
Patent
Tracks new filings at EPO, USPTO, and WIPO, prosecution deadlines, opposition windows, and unrepresented filers in your technology areas. Lexi surfaces the prospect before your competitors call.
Trademark
Renewals at EUIPO and 30+ national registers, conflicting applications, and expansion intent from brands without local counsel. Lexi flags the conflict the day it publishes.
IP Litigation
UPC, EPO opposition divisions, and national IP courts. Lexi flags new actions, tracks docket deadlines, and surfaces parties without firm representation.
What used to take our BD team an entire Monday morning now happens before I’ve finished my coffee. Lexi drafts the outreach, preps the briefings, tracks the follow-ups — and honestly, for the first time in twenty years, business development actually feels enjoyable.
