The short version

Robert Langer is listed as a director on 2 SEC Form D filings by 1 issuer between Nov 2010 and Mar 2013: DX Biosciences, Inc. (San Diego, CA — industry reported as "Other" — 2010–2013; $529K reported sold to 6 investors).

What this means One deal on file with the SEC. A Form D is the notice a company files after it starts selling a private investment — it is a notice, not an approval.

Listed alongside Frank Foster (2 shared filings), Russell Lebovitz (2 shared filings), Samir Mitragotri (2 shared filings), Dan Watkins (1 shared filing), Daniel Haimovic (1 shared filing) and 2 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Robert. Each name links to their own page.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AK, AL, AR, AZ, CA, CT, DE, FINRA, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, OK, OR, PA, RI, SC, SD, TN, TX, VT, WA, WI, WV, WY) — 12 bankruptcy cases matching the name listed in Key records below.

What this means 12 records came back. Each one is listed below with a link to the original document and a line saying why it matched. A name match is not proof it is the same person or company — read the why line and the document. Being sued or named in a release is an accusation, not a finding.

We compared 2 public filings for Robert Langer and found 8 differences: Robert Langer appears on 1 deal that stopped filing before reaching its target; Form D filed 22 days after the first sale; and more below.

What this means These are differences between the sponsor's own SEC filings — both values, dates and sources are listed in Key records, section 4. Most have ordinary explanations; ask the sponsor.

4. Differences between public sources

Comparisons cover issuers and sponsor groups — see the issuer pages under Deals

8 differences found between the filings for Robert Langer (compared 2 filings on Oct 24, 2026)

Note · Mar 7, 2013

Robert Langer appears on 1 deal that stopped filing before reaching its target

DX Biosciences, Inc. (last filing Mar 7, 2013; $529,386 sold of $1,588,154). Each has no filing in more than two years and reported under half its target sold.

What this means An issuer whose last filing is more than two years old and reported under half its target sold. The raise may have closed early or quietly stopped. Ask what happened to each.

Sources
Note · Oct 25, 2010 – Nov 16, 2010

Form D filed 22 days after the first sale — DX Biosciences, Inc.

The filing says the first sale was Oct 25, 2010. The Form D was filed Nov 16, 2010 — 22 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 7 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

Sources
Note · Feb 25, 2013 – Mar 7, 2013

No amendment in the last 12 months on an offering that may still be open — DX Biosciences, Inc. (latest filing Mar 7, 2013)

The latest filing for this offering is dated Mar 7, 2013 (first sale Feb 25, 2013). It reports $529,386 sold of $1,588,154 offered. No later amendment is in our index as of Oct 24, 2026.

What this means SEC rules expect a yearly amendment while an offering is still going. The raise may simply have ended — a Form D does not say when it closed. Ask the sponsor whether the offering closed, when, and at what amount.

Sources
Note · Oct 25, 2010 – Nov 16, 2010

No amendment in the last 12 months on an offering that may still be open — DX Biosciences, Inc. (latest filing Nov 16, 2010)

The latest filing for this offering is dated Nov 16, 2010 (first sale Oct 25, 2010). It reports $300,000 sold of $900,000 offered. No later amendment is in our index as of Oct 24, 2026.

What this means SEC rules expect a yearly amendment while an offering is still going. The raise may simply have ended — a Form D does not say when it closed. Ask the sponsor whether the offering closed, when, and at what amount.

Note · Mar 29, 2010 – Aug 27, 2026

Same name, different state: "Robert Langer" (PA) is a separate record

This page covers filings where the address state is CA. A separate record, "Robert Langer" with address state PA, is listed on 14 filings — most recently by Noveome Biotherapeutics, Inc. (Aug 27, 2026). Both records have filings in the same period (Nov 16, 2010 to Mar 7, 2013).

The two records do not overlap in time: this page runs Nov 16, 2010 to Mar 7, 2013; the other runs Apr 20, 2016 to Jun 19, 2019.

Note · Nov 16, 2010 – Mar 7, 2013

Address moved from La Jolla, CA to San Diego, CA — DX Biosciences, Inc.

The people listed on the Nov 16, 2010 filing give La Jolla, CA; on the Mar 7, 2013 filing they give San Diego, CA.

What this means Businesses move; this just shows the two places and dates. If you were told one city and the forms say another, ask which is current.

Sources
What is compared

What is compared: every Form D and D/A we hold for this subject, side by side — filing dates vs. first-sale dates (the 15-day rule), amendment timing on open offerings (the yearly-amendment expectation), amounts sold, investor counts, offering amounts and minimums across amendments, industry and size bands, addresses, how each person's name and role is written, paid sellers' CRD numbers, and (for groups) where the member companies were formed and sit. Everything is as filed by the issuer; the SEC does not check it. Differences are common and usually have ordinary explanations — we show both values, the dates, and the source so you can ask. As of Oct 24, 2026.
