PNC Bank v. Secure Axccess, LLC

Friday, October 17th, 2014

The Patent Docs website had an interesting post yesterday about recent §101 decisions by the PTAB. [Link] One decision discussed is PNC Bank v. Secure Axccess, LLC.  In that PTAB proceeding, the Board rejected an assertion that a claim directed at a computer implemented method failed to satisfy §101 under the Alice v. CLS test.   You can review the Board’s opinion by judges Barbara Benoit, Trenton Ward, and Georgianna Braden [here].

If you think this decision warrants being designated precedential by the Board, see this earlier post:  [Requesting That a Board Decision Be Made Precedential].

Federal Circuit Judges of the American Law Institute

Monday, October 6th, 2014

You might recall that the American Law Institute is the association of judges, scholars, and attorneys that formulates the various Restatements of the Law.  I have been curious why there is no Restatement of Patent Law — perhaps because there is a single intermediate appellate court.  At any rate, given the turmoil associated with 35 U.S.C. §101, among other issues, a restatement might not be a bad idea.

I was curious which Federal Circuit judges are members of the ALI.  It appears that Judges Bryson, Wallach, Dyk, and O’Malley are all members.  Congratulations to Judges Dyk and O’Malley who became members in 2013.

Riding Circuit?

Thursday, September 25th, 2014

The Federal Circuit has posted the oral argument schedule for October and November and it appears that all sessions are going to be held in D.C. this year.  Usually, the Federal Circuit sits outside of D.C. during the fall.  Perhaps the court is counting its visit to Baltimore in February as its trip for the year.  Or, perhaps the court will ride circuit to a warm weather location in December.  Florida? San Diego?  U.S. District Court of the Virgin Islands (St. Thomas and St. Croix)?  U.S. District Court for the District of Puerto Rico?  U.S. District Court for the Northern Mariana Islands?  U.S. District Court of Guam?

Here’s a list of previous locations where the court rode circuit through 2009. [List]   Since 2010, the court also rode circuit to Atlanta, Oregon, Denver, and various Third Circuit locales.

Akamai v. Limelight, Take 3

Sitting by Designation

Thursday, September 11th, 2014

george_h_wu_district_judgeThe Federal Circuit hasn’t had a district court judge sit by designation for quite some time.  During Chief Judge Rader’s tenure there was a marked decline in judges sitting by designation, as compared to his predecessor Chief Judge Michel.

Here’s one suggestion:  Judge George Wu of the Central District of California.

Got Passport?

Thursday, September 4th, 2014

Just a heads up to those of you thinking of conducting a hearing or personal interview at a USPTO facility — depending on which state you hail from, your driver’s license may not be sufficient for access.  Practitioners visiting the USPTO from Alaska, American Samoa, Arizona, Kentucky, Louisiana, Maine, Massachusetts, Minnesota, Montana, New York, Oklahoma, and Washington are at risk. See the PTO announcement below. [Link]


USPTO to Institute New Visitor Policy Effective August 4, 2014

As of August 4, 2014, the U.S. Patent and Trademark Office (USPTO) will be instituting new access control procedures that may affect visitors to the USPTO campus in Alexandria, Virginia, as well as visitors to USPTO’s satellite offices in Denver and Detroit.

These changes are the result of the Federal Government’s enforcement of the REAL ID Act, which enacts one of the key recommendations of the 9/11 Commission.  The Act establishes minimum security standards for state-issued driver licenses and identification cards and prohibits Federal agencies from accepting those documents for official purposes unless the Department of Homeland Security (DHS) determines that the state meets the minimum standards.

As of April 21, the following states do not meet the REAL ID standards:

  • Alaska
  • American Samoa
  • Arizona
  • Kentucky
  • Louisiana
  • Maine
  • Massachusetts
  • Minnesota
  • Montana
  • New York
  • Oklahoma
  • Washington

Visitors to the USPTO with state issued identification from these states must present alternate forms of identification to facilitate access.  Three of the states listed above offer an Enhanced Driver’s License that is identifiable by an American flag on the license; they are New York, Minnesota, and Washington.  USPTO will accept the Enhanced Driver’s Licenses from those states.

DHS currently accepts other forms of Federal-issued identification in lieu of a state-issued driver’s license, such as a:

  • Passport
  • Passport card
  • DoD’s CAC
  • Federal agency HSPD-12 ID
  • Veterans ID
  • Military dependents ID
  • Trusted Traveler card – Global Entry, SENTRI, or NEXUS
  • Transportation Workers Identification Credential (TWIC)

For visitors using state-issued ID to access the USPTO, only driver’s licenses or identification cards from states that meet Federal standards will be honored.  USPTO will continue to accept other forms of government-issued identification, including Federal employee badges, passports, military identification cards, or Enhanced Driver’s Licenses as noted above.

If visitors do not have acceptable identity documents, the person to be visited at USPTO will need to provide an escort in order for the visitor to access the USPTO. The visitor must be escorted at all times while in USPTO secured areas.

Headings and Boilerplate, Hill-Rom v. Stryker

Thursday, August 14th, 2014

The Hill-Rom v. Stryker case decided in June has not gotten a lot of coverage.  There are some interesting portions of the opinion that will appeal to patent prosecutors.

Present Invention

Judge Moore, writing for the court, gave a summary of recent case law and when the use of the term “present invention” can be limiting:

Disavowal requires that “the specification [or prosecution history] make[] clear that the invention does not include a particular feature,” SciMed Life Sys., Inc. v. Advanced Cardiovascular Sys., Inc., 242 F.3d 1337, 1341 (Fed. Cir. 2001), or is clearly limited to a particular form of the invention, Edwards Lifesciences LLC v. Cook Inc., 582 F.3d 1322, 1330 (Fed. Cir. 2009) (”[W]hen the preferred embodiment is described in the specification as the invention itself, the claims are not necessarily entitled to a scope broader than that embodiment.”) (quotation omitted). For example, we have held that disclaimer applies when the patentee makes statements such as “the present invention requires . . .” or “the present invention is . . .” or “all embodiments of the present invention are . . . .” See Regents of Univ. of Minn. v. AGA Med. Corp., 717 F.3d 929, 936 (Fed. Cir. 2013)Honeywell Int’l, Inc. v. ITT Indus., Inc., 452 F.3d 1312, 1316-19 (Fed. Cir. 2006)SciMed, 242 F.3d at 1343-44;Astrazeneca AB v. Hanmi USA, Inc., 554 F. App’x 912, 915 (Fed. Cir. 2013) (nonprecedential). We have also found disclaimer when the specification indicated that for “successful manufacture” a particular step was “require[d].” Andersen Corp. v. Fiber Composites, LLC, 474 F.3d 1361, 1367 (Fed. Cir. 2007) (”Those statements are not descriptions of particular embodiments, but are characterizations directed to the invention as a whole.”). We found disclaimer when the specification indicated that the invention operated by “pushing (as opposed to pulling) forces,” and then characterized the “pushing forces” as “an important feature of the present invention.”SafeTCare Mfg., Inc. v. Tele-Made, Inc., 497 F.3d 1262, 1269-70 (Fed. Cir. 2007). We found disclaimer when the patent repeatedly disparaged an embodiment as “antiquated,” having “inherent inadequacies,” and then detailed the “deficiencies [that] make it difficult” to use. Chicago Bd. Options Exch., Inc. v. Int’l Sec. Exch., LLC, 677 F.3d 1361, 1372 (Fed. Cir. 2012) (”[T]he specification goes well beyond expressing the patentee’s preference . . . and its repeated derogatory statements about [a particular embodiment] reasonably may be viewed as a disavowal . . . .”). Likewise, we found disclaimer limiting a claim element to a feature of the preferred embodiment when the specification described that feature as a “very important feature . . . in an aspect of the present invention” and disparaged alternatives to that feature. Inpro II Licensing, S.A.R.L. v. T-Mobile USA Inc., 450 F.3d 1350, 1354-55 (Fed. Cir. 2006).

There is no such disclaimer or lexicography here. There are no words of manifest exclusion or restriction. The patents-in-suit do not describe the invention as limited to a wired datalink. There is no disclosure that, for example, the present invention “is,” “includes,” or “refers to” a wired datalink and there is nothing expressing the advantages, importance, or essentiality of using a wired as opposed to wireless datalink. Nor is there language of limitation or restriction of the datalink. Nothing in the specification or prosecution history makes clear that the invention is limited to use of a cable as a datalink. Absent such language, we do not import limitations from the specification into the claims.

At another point in the opinion, Judge Moore, writing for the court, noted with respect to a different claim term:

The fact that the specification indicates that in one embodiment, messages are sent to the wall interface unit “in accordance with the present invention,” does not mean that a wall interface unit must be present in all embodiments of the invention.

During oral argument, Judge Moore made the following comments about “embodiments of the present invention”:  [Listen].


The opinion also took into account boilerplate, as well as a heading from the specification.  Namely, the opinion stated:

In fact, this specification states that the figures depicting the use of a wired datalink merely “illustrate embodiments of the invention.” `038 patent col. 4 ll. 59-65; see also id. col. 5 ll. 30-31 (”DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS”); id.col. 22 ll. 20-31 (the “description of various embodiments” is not intended “to restrict or in any way limit the scope of the appended claims to such detail”).

I’ve reproduced these sections below.




What particularly caught my eye was the mention of the heading “Detailed Description of Specific Embodiments.”  I think many prosecutors these days follow the philosophy of just using the heading “Detailed Description.”  You can judge for yourself  in view of this case whether the Federal Circuit has given a stamp of approval to “Detailed Description of Specific Embodiments” as being non-limiting.

Doctrine of Claim Differentiation

The CAFC has been a little bit schizophrenic in how it treats the doctrine of claim differentiation.  In the Hill-Rom v. Stryker oral argument, Judge Schall had the following comments about the role of the doctrine of claim differentiation after Phillips v. AWH:  [Listen]. In the Hill-Rom opinion, Judge Moore, writing for the court, noted that the doctrine of claim differentiation creates a presumption that a limitation added by a dependent claim is not required by the independent claim:

The only distinction between claim 1 and claim 2 is the limitation that the “datalink” is a wired datalink. See also 10, 18. “[T]he presence of a dependent claim that adds a particular limitation raises a presumption that the limitation in question is not found in the independent claim.” Liebel-Flarsheim, 358 F.3d at 910. This presumption is especially strong where the limitation in dispute is the only meaningful difference between an independent and dependent claim. Id. Of course, claim differentiation is not a hard and fast rule, and the presumption can be overcome by a contrary construction required by the specification or prosecution history. Seachange Int’l, Inc. v. C-COR, Inc., 413 F.3d 1361, 1369 (Fed. Cir. 2005). However, nothing in this specification or prosecution history rebuts the presumption established by the doctrine of claim differentiation.

Hill-Rom v. Stryker, __ F.3d __ (Fed. Cir. 2014).

Note also what the Phillips v. AWH en banc court said about the DOCD:

Other claims of the patent in question, both asserted and unasserted, can also be valuable sources of enlightenment as to the meaning of a claim term. Vitronics, 90 F.3d at 1582. Because claim terms are normally used consistently throughout the patent, the usage of a term in one claim can often illuminate the meaning of the same term in other claims. See Rexnord Corp. v. Laitram Corp., 274 F.3d 1336, 1342 (Fed.Cir.2001); CVI/Beta Ventures, Inc. v. Tura LP, 112 F.3d 1146, 1159 (Fed.Cir.1997). Differences among claims can also be a useful guide in understanding the meaning of particular claim terms. See Laitram Corp. v. Rexnord, Inc., 939 F.2d 1533, 1538 (Fed.Cir.1991). For example, 1315*1315 the presence of a dependent claim that adds a particular limitation gives rise to a presumption that the limitation in question is not present in the independent claim. See Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 910 (Fed.Cir.2004).

Phillips v. AWH, 415 F.3d 1303, 1314-15 (Fed. Cir. 2008).

In contrast to Hill-Rom v. Stryker, a panel in a recent opinion made no reference to the DOCD presumption.

We now turn to the extent it should inform the claim

construction. Albecker’s position is that “if claim 11

depends on claim 10, it is axiomatic that claim 10 is broad

enough to include embodiments that have a top cushion

which is integral and continuous with the foundation.”

Appellant’s Br. 8. This is essentially a claim differentiation

argument. And, importantly, “[c]laim differentiation

is a guide, not a rigid rule.” Laitram Corp. v. Rexnord,

Inc., 939 F.2d 1533, 1538 (Fed. Cir. 1991)) (quoting Auto

giro Co. of Am. v. United States, 384 F.2d 391, 404 (Ct. Cl.

1967)); see also Seachange Int’l, Inc. v. C–COR, Inc., 413

F.3d 1361, 1369 (Fed. Cir. 2005) (reiterating that claim

differentiation is “not a hard and fast rule and will be

overcome by a contrary construction dictated by the

written description or prosecution history” (citation

omitted)). Thus, our task is to determine if the evidence

supporting the district court’s construction is strong

enough to overcome Albecker’s claim differentiation


Albecker v. Contour Products, Inc., 2014-1318 (Fed. Cir. Aug. 7, 2014).


The opinion in Albecker later concludes:

Accordingly, we hold that the presence of claim 11 is

insufficient to overcome the strong evidence in the claims,

specification, prosecution history, and reexamination

record that the district court’s construction is correct.

Albecker v. Contour Products, Inc., 2014-1318 (Fed. Cir. Aug. 7, 2014).

Denver PTAB Blazes New Trails

Wednesday, August 6th, 2014

You might have noticed last week that the PTAB designated a ruling concerning the AIA as “precedential.”  [Opinion].   This is the first ruling concerning the AIA to be given precedential status by the PTAB.  It is interesting to note that two of the three judges on this opinion hail from the Denver office of the PTAB.  The Denver PTAB moved into its permanent offices just recently (on June 30th); so, it is good to see the judges already blazing new trails through the AIA forest.
