Industries We Serve

Biotech & Pharmaceutical

Counsel to therapeutics ventures and the capital behind them on corporate structure, staged financing, licensing and IP, and the regulatory pathway, kept aligned across the long arc from discovery to commercialization.

A new chemical entity gets five years of data exclusivity on approval and a biologic twelve, and a patent can be extended by up to five years for time lost in regulatory review. Those clocks run alongside the patent's twenty-year term, a licensee or an acquirer prices both, and they start on dates the company only partly controls. The other variable is the chain of title. An agreement in which an inventor agrees to assign an invention transfers nothing until a second document is signed, a distinction the courts have enforced for more than a decade and one that still surfaces in diligence.

We act for therapeutics and platform companies and for the funds and family offices that finance them, on formation, staged financing and the licensing deals through which value moves. We negotiate the upfront, the milestones and the royalty tiers alongside the terms that decide who controls development and what reverts on termination. Patent prosecution and FDA submissions are handled by registered patent counsel and regulatory affairs specialists we coordinate with, so the filings and the deal documents say the same thing.

What we do

Corporate, capital, and IP counsel for biotech and pharmaceutical ventures, from formation through partnering, approval strategy, and exit.
01

Formation & Corporate Structuring

Entity selection, founder and equity arrangements, and holding structures for a science-led company that can carry a long development timeline, multiple financing rounds, and an eventual partnering or exit.

02

Venture & Growth Financing

Seed instruments, priced venture and growth rounds, milestone- and royalty-based deals, and venture-debt facilities, structured so the cap table holds through the staged, milestone-driven way biotech capital arrives.

03

Licensing, Collaboration & Partnering

Out-licensing, in-licensing, research collaborations, option and co-development arrangements, and supply agreements, with upfronts, milestones, and royalties negotiated alongside the control terms that decide ownership and development rights.

04

Intellectual Property & Trade Secrets

IP licensing, assignment, ownership diligence, and the IP terms inside financings and deals, coordinated with registered patent counsel where prosecution or patent opinion work is required, so filings and deal documents reinforce one another.

05

FDA & Regulatory Strategy

The legal and commercial dimensions of the approval pathway, meaning how development strategy shapes financing, licensing, and diligence, coordinated with registered regulatory counsel for product-specific submission and approval work.

06

M&A, Acquisitions & Exit

Acquisitions, asset deals, and exits for therapeutics and platform companies, managing IP, regulatory, and contractual diligence so the corporate, scientific, and regulatory questions are answered together.

What you should know

The realities that shape how a biotech or pharmaceutical venture is structured.
01

Federal money follows the patent

If federal funding touched the science, Bayh-Dole attaches: the university keeps title, the government holds a paid-up license and march-in rights, and an exclusive licensee must manufacture substantially in the United States absent a waiver. Seek the waiver before the supply chain is designed, not after a buyer asks.

02

The second tranche is a negotiation

A tranched Series A funds the IND and an early readout in two closings, and the second is an investor obligation conditioned on data. A missed milestone turns it into a negotiation, usually with a repricing, so we draft the milestone definition as carefully as the valuation.

03

The Orange Book is a strategy

For a small-molecule drug, only patents listed in the Orange Book force a generic to certify against them, and a Paragraph IV certification opens a 45-day window to sue and earn the 30-month stay. A patent left off the list earns no stay. Listing is decided at approval.

04

The biosimilar dance is optional

A biologic's twelve years of exclusivity run from first licensure, and the statutory information exchange that follows is optional for the applicant, so the reference sponsor may learn of a competing application only when the biosimilar maker chooses. The patent estate is built to be litigated without that schedule.

05

Reversion outlasts the royalty

In a collaboration, who owns an improvement the partner makes with the licensed compound, what reverts on termination and whether the license survives the partner's acquisition by a competitor decide the company's option value more than the royalty rate does. Each is drafted as if the deal will end badly.

06

Trials go where the patients are

A Delaware parent holds a European subsidiary that sponsors EU studies under the Clinical Trials Regulation via one CTIS application, while the patents stay with the parent under an intercompany license. That license and its data-transfer terms are what the tax authority, the auditor and the acquirer each trace.

The arc of a molecule

How this work runs

From first assignment to the exclusivity clock.
  1. Stage 01

    Chain of title

    Before any term sheet, every founder, advisor, and academic collaborator assigns their inventions to the company and the university license is read against the science it covers. A single unassigned inventor discovered in Series B diligence can reprice the round, so the patent estate's chain of title is closed at formation rather than repaired later.

  2. Stage 02

    Milestone-staged capital

    Each round is priced against a data readout that hasn't happened yet, so the documents anticipate the tranche that funds the IND, the anti-dilution math that survives a down round after a failed cohort, and the pro-rata rights strategic investors will demand before the Phase 2 data lands.

  3. Stage 03

    The partnering inflection

    When a pharma partner arrives, the economics of upfront payment, development milestones, and tiered royalties are negotiated alongside the terms that decide the company's future: who owns improvements, who controls the development plan, what reverts on termination, and what happens to the license on change of control.

  4. Stage 04

    Exit against the clock

    A buyer prices the asset off the approval pathway and the exclusivity runway: patent term, regulatory exclusivity, and the generics horizon. Diligence closes IP, regulatory, and contractual questions as one workstream, with CVRs bridging the gap between what the seller believes the data is worth and what the buyer will pay today.

In this sector the patent estate is the company, and every financing, license, and exit is a corporate decision made in its shadow.

Frequently asked

Common questions on biotech and pharmaceutical counsel.
What kinds of biotech and pharmaceutical clients do you act for?

Hart David Carson LLP acts for therapeutics and platform companies across the development arc, from early discovery ventures and clinical-stage biotechs to specialty and generic pharmaceutical businesses and the contract research and manufacturing organizations that support them. We also act for the venture funds, family offices, and strategic investors who finance them. The common thread is a science-led business where corporate structure, capital, intellectual property, and regulatory pathway all have to line up before value can be realized.

Do you handle FDA and regulatory matters for drug developers?

We advise on what the pathway does to the deal, and we leave the submission itself to the regulatory affairs specialists we coordinate with. The pathway sets the terms: an orphan designation adds seven years of market exclusivity and changes what a licensee will pay; a breakthrough or fast-track designation shortens the time to a readout and so the time to the next tranche; a complete response letter is a defined event in most financing and collaboration documents, with consequences written in advance. We draft those consequences, keep the regulatory timetable and the financing timetable on one calendar, and read the investigational new drug and pre-submission correspondence for what it commits the company to. The FDA is the regulator this work answers to, and the file we build is the one its reviewers and a buyer's diligence team will both read.

How do you approach intellectual property for a biotech?

For a therapeutics venture the patent estate and trade-secret program are often the principal asset, so we treat IP as a corporate question from the first day. We handle licensing, collaboration, and assignment agreements, freedom-to-operate and ownership diligence, and the IP terms inside financings and M&A. Where patent prosecution or patent opinion work is required, we coordinate with registered patent counsel so the filings and the deal documents reinforce one another.

What financing work do you do for biotech and pharma companies?

We structure and document the full capital arc: convertible and SAFE instruments at the seed stage, priced venture and growth equity rounds, milestone- and royalty-based deals, and venture-debt facilities. Biotech capital is staged against scientific milestones, so the terms have to anticipate dilution, future rounds, and partnering or exit scenarios. We build the cap table and the financing documents to hold through that whole sequence rather than through the current round alone.

Do you handle licensing, collaboration, and partnering deals?

Yes. Out-licensing, in-licensing, research collaborations, option and co-development arrangements, and supply and manufacturing agreements are central to how value moves in this sector. We negotiate the economics of upfronts, milestones, and royalties alongside the control terms that decide who owns improvements, who runs development, and what happens on change of control, so the agreement protects the company well beyond signing.

Can you coordinate a cross-border biotech structure?

Yes. The usual shape is a Delaware parent that holds the patents and raises the capital, a subsidiary in the jurisdiction where the trials run, and sometimes a manufacturing or research entity in a third. Three documents hold that shape together: the intercompany license that lets the subsidiary use the patents and sets a royalty the tax authorities on both sides will accept, the clinical trial agreements that assign data and inventions back to the parent, and the data-transfer terms that let patient-level data cross borders lawfully. A Series B investor or an acquirer traces all three, and a redomiciliation later is expensive precisely because they were not designed to move. We coordinate the structure with locally admitted counsel in each jurisdiction and set it up once, early, to be sold.
