In August of 2005, the PTO revised the MPEP to include a new section 2111.04.  This new section of the MPEP addressed the language “adapted to.”  While the new section of the MPEP cited case law for other phrases, such as “whereby” clauses, no legal support was cited in regard to the “adapted to” language.  Eight years and six revisions of the MPEP later, no legal support has yet been cited.  Section 2111.04 is reproduced below:

2111.04   “Adapted to,” “Adapted for,” “Wherein,” and “Whereby” Clauses [R-9]

Claim scope is not limited by claim language that suggests or makes optional but does not require steps to be performed, or by claim language that does not limit a claim to a particular structure. However, examples of claim language, although not exhaustive, that may raise a question as to the limiting effect of the language in a claim are:

(A) “adapted to” or “adapted for” clauses;

(B) “wherein” clauses; and

(C) “whereby” clauses.

The determination of whether each of these clauses is a limitation in a claim depends on the specific facts of the case. > See, e.g., Griffin v. Bertina, 283 F.3d 1029, 1034, 62 USPQ2d 1431 (Fed. Cir. 2002)(finding that a “wherein” clause limited a process claim where the clause gave “meaning and purpose to the manipulative steps”). < In Hoffer v. Microsoft Corp., 405 F.3d 1326, 1329, 74 USPQ2d 1481, 1483 (Fed. Cir. 2005), the court held that when a “‘whereby’ clause states a condition that is material to patentability, it cannot be ignored in order to change the substance of the invention.” Id. However, the court noted (quoting Minton v. Nat’l Ass’n of Securities Dealers, Inc., 336 F.3d 1373, 1381, 67 USPQ2d 1614, 1620 (Fed. Cir. 2003)) that a “‘whereby clause in a method claim is not given weight when it simply expresses the intended result of a process step positively recited.’” Id.

It is worth noting that in the recent case of Broadcom Corporation v. EMULEX CORPORATION, No. 2012-1309 (Fed. Cir. Oct. 7, 2013) an “adapted to” phrase was at issue in the appeal. The claim at issue was claim 8 which recited:

8. A communication device configured to receive multiple serial data signals, comprising:

a master timing generator adapted to generate a master timing signal;

multiple receive-lanes each configured to receive an associated one of the multiple serial data signals, each receive-lane including

a phase interpolator adapted to produce a sampling signal having an interpolated phase, and

a data path adapted to sample and quantize the associated serial data signal in accordance with the sampling signal; and

an interpolator control module coupled to each receive-lane, the interpolator control module being adapted to cause the phase interpolator in each receive-lane to rotate the interpolated phase of the sampling signal in the receive-lane at a rate corresponding to a frequency offset between the sampling signal and the serial data signal associated with the receive-lane so as to reduce the frequency offset between the sampling signal and the serial data signal.

The court in Broadcom noted that the determination of infringement at the district court level had turned on a particular limit in claim 8 — a closer look at claim 8 reveals that the language at issue was actually part of an “adapted to” claim.  The Federal Circuit stated:

At trial, the district court found that, at bottom, infringement turned on whether the accused products “reduced the offset between the sampling signal and the data signal all of the time or only some of the time.” J.A. 35. Importantly, the district court found that Emulex’s expert, Dr. Nikolic, conceded that the accused device “reduced the offset at least some of the time.” J.A. 640; see Oral Argument at 1:19-1:48, Broadcom Corp. v. Emulex Corp., No. 2012-1309, available at http:// www.cafc.uscourts.gov/oral-argument-recordings/12-1309/ all. It is well settled that an accused device that “sometimes, but not always, embodies a claim[] nonetheless infringes.” Bell Commc’n Research, Inc. v. Vitalink Commc’n Corp., 55 F.3d 615, 622-23 (Fed. Cir. 1995). Accordingly, this court affirms the district court’s grant of JMOL that Emulex’s accused products infringed the ‘150 patent and denial of Emulex’s JMOL of noninfringement.

Thus, the Federal Circuit affirmed the finding of infringement based on language appearing in an “adapted to” limitation.

Incidentally, this past week the US Patent Office issued at least 500 patents that include “adapted to” in one or more claims.

While some examiners at the PTO push back on the limiting effect of “configured to” or “capable of” claim language in apparatus claims and other examiners do not, the Federal Circuit typically treats such language as limiting during litigation.  The recent oral argument of Bally Technologies, Inc. v. Business Intelligence Systems Solutions, Inc., App. No. 2013-1131 (Fed. Cir. Nov. 8, 2013) not only highlights that the Federal Circuit treats such language as limiting but it also raises some questions about apparatus claims that recite a claim element as “configured to [achieve a particular result].”

The Federal Circuit panel merely issued a Rule 36 judgment.; however, you can review the relevant district court order [here] for more background.  An example of a claim at issue in the case was claim 1 of the ‘367 patent:

1.  A data visualization system comprising . . . a contour generator configured to generate and display one or more contour lines at least partly around each data point or group of data points, each contour line representing data values that are less than the data value[] of the data point[] around which the contour line is displayed.

The relevant discussion concerning the “configured to” language is available [here].

Some of the questions raised were:

1) Does use of the phrase “configured to [produce a particular result]” in an apparatus claim require that the result be produced every time the apparatus is used rather than just some of the time?

2)  Does the case law that addresses claims using the phrase “capable of” apply to claims that recite “configured to?”  For example, does the Finjan case apply to “configured to” claims.

At one point during the oral argument, the appellant mentioned a district court case from August concerning Versata.  Apparently the judge in that case treated “configured to” language and “capable of” language differently.  I wasn’t able to locate a link to the Versata opinion.

In the recent  oral argument of Finn v. Rea, App. No. 2012-1635 (Fed. Cir. Oct. 16, 2013) a panel of the Federal Circuit once again dealt with a written description issue.  The panel confronted the tension in the court’s case law between cases like In re Huston, 308 F.3d 1267, 1277 (Fed. Cir.2002) which states that for written description:

“Entitlement to a filing date does not extend to subject matter which is not disclosed, but would be obvious over what is expressly disclosed. It extends only to that which is disclosed” (citing Lockwood v. American Airlines, 107 F.3d at 1571-72 (Fed. Cir. 1997)

and cases like Nazomi Communications, Inc. v. ARM Holdings, PLC, 403 F.3d 1364, 1369 (Fed.Cir.2005) which was cited by the court in Philips v. AWH, 415 F.3d 1303 (Fed. Cir. 2005)(en banc) and noted that for purposes of claim construction claims may embrace “different subject matter than is illustrated in the specific embodiments in the specification.”

Judge Taranto framed the question this way [Listen], while Judge Prost asked where the line should be drawn in this way [Listen].

Judge Taranto also noted that in the past he had tried to think of written description by asking whether the difference between what was originally described and what is now claimed raises any non-trivial technical issues that somebody would have to solve: [Listen].

The Supreme Court of the United States heard oral argument today in the case of Medtronic, Inc. v. Boston Scientific Corp.  You can review the transcript of the oral argument here: [Transcript].

In the recent oral argument of Laube v. Rea, a panel of the Federal Circuit was trying to determine whether a patent specification had the degree of specificity required to satisfy the written description requirement for a claim that was not disclosed as a single embodiment in the specification.  The claim at issue required a “spring clip” which was illustrated in one embodiment and a “side plate” which was illustrated in a different embodiment.  The panel wanted to know what degree of specificity short of an in haec verba description would satisfy the written description standard. [Listen]

The patent owner noted that the specification included standard boilerplate language that indicated pieces could be mixed and matched.  I found it curious that the panel seemed willing to discount that boilerplate language due to the fact that such language appears in most patents: [Listen].

Having identified an interesting issue with respect to written description and having noted that the Federal Circuit’s decisions don’t necessarily provide a coherent and useful test to resolve the issue at hand, the panel promptly issued a Rule 36 judgment: [Opinion].
