13 months ago I wrote about the Defensive Patent License, in particular in relation to free/open source software (followup, 1993 predecessor). Today the DPL project released DPL 1.1 and announced the first licensor; see Internet Archive and EFF posts.

(The EFF post references its earlier guide to alternative patent licensing which I meant to critique, probably along lines of a partially overalpping guide to reform proposals, see patent reform, parts deficient in commons and compare with protect commons from patents. I noticed today that one of the other alternative licensing schemes, License On Transfer, seems to be getting some uptake.)

Most of what I wrote previously about the DPL concept still applies with DPL 1.1 (interesting concept, possibility of substantial good impact in long term). The new version makes one major improvement (especially in relation to FLOSS) — the exclusion of “clone” products or services from the license grant has been removed. Another small (as in a -3 words difference) improvement is that alleging patent invalidity against another DPL user no longer breaches one’s licenses (only alleging infringement does), invalidation being a defensive tactic.

DPL 1.1 also adds the requirement of explicit acceptance, which strikes me as burdensome: one must research licensed patents in order to figure out which DPL users to contact with acceptance, or regularly contact all known DPL users with acceptance of all licensed patents. I understand from the DPL 1.1 announcement telecon that formal acceptance was added because the license grant is more likely to stand up in court with such explicit acceptance, with that more likely assessment based on differences between patent and copyright, and between clubs and public licenses — and further that the “contact all known DPL users” practice will in the future be facilitated by the DPL website.

Finally, a very minor issue: DPL 1.1 reproduces the GPL’s confusing three-option version compatibility scheme (this-version-or-later, only-this-version, or any-version-if-none-specified). If one must have options, I consider less confusing this-version-or-later as default, with option to explicitly mandate only-this-version.

Congratulations and thanks to Jason Schultz, Jennifer Urban, Brewster Kahle, John Gilmore, and others for getting the DPL into production. I hope it is wildly successful; check out the DPL website and help update the Wikipedia article.

Following is a wdiff between DPL 1.0 and 1.1 in two parts (because 1.0 put definitions at the beginning, 1.1 puts them at the end) below, excluding 1.1’s preface, which has no equivalent in 1.0.

DPL 1.0-1.1 wdiff: Grant, conditions, etc.

[-2.-]{+1.+} License Grant

Subject to the conditions and limitations of this [-License and upon-]
[-affirmative assent to the commitments specified in Section 1.7 from an-]
[-individual DPL User,-] {+License,+} Licensor hereby
grants and agrees to grant to [-such-] {+any+} DPL User {+(as defined in Section 7.6) who+}
{+follows the procedures for License Acceptance (as defined in Section 1.1)+}
a worldwide, royalty-free, no-charge, non-exclusive, irrevocable (except
as stated in Sections [-3(e)-] {+2(e)+} and [-3(f))-] {+2(f))+} license, perpetual for the term of
the relevant Licensed Patents, to make, have made, use, sell, offer for
sale, import, and distribute Licensed Products and Services that would
otherwise infringe any claim of Licensed Patents. A Licensee’s sale
of Licensed Products and Services pursuant to this agreement exhausts
the Licensor’s ability to assert infringement [-by-] {+against+} a downstream
purchaser or user of the Licensed Products or Services.

[-2.1-] {+Licensor’s+}
{+obligation to grant Licenses under this provision ceases upon the arrival+}
{+of any applicable Discontinuation Date, unless that Date is followed by+}
{+a subsequent Offering Announcement.+}
{++}
{+1.1+} License Acceptance

In order to accept this License, Licensee must {+qualify as a DPL User+}
{+(as defined in Section 7.6) and must+} contact Licensor via the
[-contact-] information
provided in [-Section 1.16 and-] {+Licensor’s Offering Announcement to+} state affirmatively that
Licensee accepts the terms of this License. Licensee must also {+communicate+}
{+the URL of its own Offering Announcement (as defined in Section 7.13) and+}
specify whether it is accepting the License to all Licensor’s Patents or
only a subset of those Patents. If Licensee is only accepting the License
to a subset of Licensor’s Patents, Licensee must specify each individual
{+Patent’s country of issuance and corresponding+} patent [-by patent number.-]
[--]
[-3.-] {+number for which+}
{+it is accepting a License. There is no requirement that the Licensor+}
{+respond to the Licensee’s affirmative acceptance of this License.+}
{++}
{+2.+} License Restrictions

Notwithstanding the foregoing, this License is expressly subject to and
limited by the following restrictions:

(a) No Sublicensing. This License does not include the right to sublicense
any Licensed Patent of any Licensor.

(b) License Extends Solely to Licensed Patents in Connection with Licensed
Products and Services. For clarity, this License does not purport to
grant any rights in any Licensor’s copyright, trademark, trade dress,
design, trade secret, other intellectual property, or any other rights of
Licensor other than the rights to Licensed Patents granted in Section 2,
nor does the License cover products or services other than the Licensed
Products and Services.  {+For example, this License would not apply to+}
{+any conduct of a Licensee that occurred prior to accepting this License+}
{+under Section 1.1.+}

(c) Scope. This License does not include Patents with a priority date
or Effective Filing Date later than Licensor’s last Discontinuation
Date that has not been followed by a subsequent Offering Announcement
by Licensor.

(d) Future DPL Users. This License does not extend to any DPL User whose
Offering Announcement occurs later than Licensor’s last Discontinuation
Date that has not been followed by a subsequent Offering Announcement
by Licensor.

(e) Revocation and Termination Rights. Licensor reserves the right to
revoke and/or terminate this License with respect to a particular Licensee [-if:-]
{+if, after the date of the Licensee’s most recent Offering Announcement:+}
{++}
{+i.+} Licensee makes any Infringement Claim, not including Defensive Patent
Claims, against a DPL User; or

{+ii.+} Licensee {+assigns, transfers, or+} grants an exclusive [-license,-]
[-    with the right to sue, or assigns or transfers-] {+license for+}
a Patent to an entity or individual other than a DPL User without
conditioning the [-transfer-] {+assignment, transfer, or exclusive license+} on the [-transferee-]
{+recipient+} continuing to abide by the terms of this [-License.-] {+License, including but+}
{+not limited to the revocation and termination rights under this Section.+}

(f) Optional Conversion to FRAND Upon Discontinuation. [-As-] {+Notwithstanding+}
{+any other provision in this License, as+} of any particular Licensee’s
Discontinuation Date, Licensor has the right to convert the License of
that particular Licensee from one that is royalty-free and no-charge to
one that is subject to Fair, Reasonable, And Non-Discriminatory (FRAND) [-terms.-]
[--]
[-4.-]
{+terms going forward. No other terms in the license may be altered in+}
{+any way under this provision.+}
{++}

[-originally accepted pursuant to Section 2.1,-] {+terms and conditions either of that+}
{+numbered version+} or [-under-] {+of any later version published by one of+} the [-terms-] {+license+}
{+stewards. If Licensor does not specify a version number+} of {+the DPL in+}
{+her Offering Announcement, Licensee may choose+} any
[-subsequent-] version {+ever+} published
