`“The Person of Ordinary Skill in the Art.” Ex. 2003 ¶21.
`
`• “Patent Owner submits that the ordinary skilled artisan would
`be a person skilled in the field of roofing materials such as
`asphalt shingles. Such a person would have a bachelor's degree
`and approximately 3-5 years of additional training and
`experience in the field of manufacturing roofing materials with
`asphalt substrates. (Ex. 2003 Todd Decl., ¶22 and Ex. 2004
`Bohan Decl., ¶22).” Paper 16, pg.13.

`“The Person of Ordinary Skill in the Art.” Ex. 2003 ¶21.
`
`•
`
`“[Petitioner submits that] one of ordinary skill would be familiar with
`various methods of printing polymer on various substrates and for various
`purposes (see generally Lassiter, Hefele, Bayer, Eaton, Allman, Jackson,
`and Lalwani). (Ex. 1014, Levenson Dec., ¶ 12).[…] would understand
`various types of polymers can be printed using these methods […] would
`be aware various methods of printing polymer are interchangeable and
`provide for predictable results […] would possess at least a bachelor’s
`degree with knowledge of various printing methods and several years of
`industry experience in the printing field.” Paper 1, pg. 14.

`“Paper is not a roofing a building cover material.”
`
`Paper 16, pg. 2.
`
`Ed Todd:
`•
`“As is commonly understood by a person of ordinary skill in the art and
`even a layperson, the purpose of a roof is to shed water and help
`weatherproof a building.” Ex. 2003 ¶64.
`
`
`
`•
`
`•
`
`“As is commonly known, and as has been further confirmed by printing
`expert Dr. Mark Bohan, paper is not waterproof.” Ex. 2003 ¶63.
`
`
`
`“As a reasonable expert in roofing, I know that untreated paper is not a
`recognized roofing or building cover material.” Ex. 2003 ¶65.

`

`
`“Paper is not a roofing a building cover material.”
`
`Paper 16, pg. 2.
`
`Dr. Mark Bohan:
`
`
`
`• “The Lassiter ‘409 patent does not suggest paper is a roofing
`cover material in any way.” Ex. 2004 ¶33.
`
`
`
`• “The Lassiter ‘409 patent makes it very clear that ‘paper,’
`along with rag and fiberglass are potential starting materials
`for dry felt. He makes it equally clear that dry felt only
`becomes a roofing underlayment after it has been saturated
`with an asphalt material.” Ex. 2004 ¶35.

`
`“[N]ail tabs and their precursor tin or plastic caps are employed to
`provide strength or reinforcement to roofing cover materials.”
`Paper 16, pg. 21.
`
`
`
`
`Ed Todd:
`
`
`•
`
`•
`
`“Asphalt saturated substrate can be torn or damaged quite easily. This is
`why the installation of roofing underlayment requires an additional
`fastening reinforcement of some kind.” Ex. 2003 ¶49.
`
`
`
`“The integrated nail tabs developed by Lassiter and Collins provides a
`visible, reinforcing nail tab, already bound to the roofing material to
`facilitate installation.” Ex. 2003 ¶51.

`
`“A Non-Contact Process Is Completely Distinct From A
`Contact Process.”
`
`Ex. 2004 ¶43.
`
`Dr. Mark Bohan:
`•
`“There is a significant difference between a non-contact and contact
`process from both a physical and chemical perspective. In many cases it
`would not be obvious or advisable to move from a non-contact to a contact
`process.” Ex. 2004 ¶44.
`
`
`Ed Todd:
`•
`“[N]o one skilled in the art of roofing manufacturing would want to risk
`breaking the sheet by using a contact operation as opposed to a non-contact
`operation.” Ex. 2003 ¶66.

`
`
`“[T]he asphalt used during the manufacture of roofing and building cover
`materials with Nail Tabs can readily transmit oils or other asphalt contaminates
`to the equipment making the product.” Ex 2003 ¶70.
`
`
`
`Ed Todd:
`
`
`• “Due to the nature of these continuous operations, even minor
`contamination issues can quickly escalate.” Ex. 2003 ¶70.

`
`“Paper is not a roofing a building cover material.”
`
`Paper 16, pg. 2.
`
`Ed Todd:
`
`
`
`• “Because untreated paper is certainly not a recognized form of
`roofing or building cover material, I do not believe there
`would be any reason someone skilled in the art of making
`roofing products would ever look to the printing field or the
`cited secondary references for a solution to the problem of
`reinforcing roofing or building cover materials.” Ex. 2003 ¶63.

`
`

`
`“Paper is not a roofing a building cover material.”
`
`Paper 16, pg. 2.
`
`Dr. Mark Bohan:
`
`
`
`• “The assertion that ‘[p]aper is a recognized form of roofing or
`building cover material’ is entirely divorced from both the
`teachings of Lassiter and the common understanding of what
`is referred to as ‘paper’ in the printing industry.” Ex. 2004 ¶35.
`
`
`
`• “Treating asphalt saturated felt as if it were a traditional paper
`is an unreasonable substitution and will not lead to expected
`results.” Ex. 2004 ¶40.

`
`“Dr. Levenson’s Declaration.”
`Ex 2004 ¶102.
`
`Dr. Mark Bohan:
`
`
`“I am unable to understand Dr. Levenson’s repeated assertion that ‘[p]aper
`is a form of recognized roofing or building cover material.’” Ex. 2004 ¶103.
`
`
`
`“Upon reviewing the language of the Lassiter patent that Dr. Levenson
`cites to support his assertion, I am left puzzled as to how he reached this
`conclusion.” Ex. 2004 ¶103.
`
`
`
`“As discussed previously, the physical properties that define something as a
`‘paper’ are almost entirely different from the physical properties inherent in
`asphalt saturated felt.” Ex. 2004 ¶103.

`analysis relied on his understanding that ‘the only requirement
`a nail tab has to have in the context of the '757 patent’ is ‘that
`it identifies where the nails are to be inserted’ as that is ‘the
`goal of the nail tab’. (Ex. 2005, pp. 82-3 of depo.). As a result
`and as further explained below, this fundamental
`misunderstanding, which does not contemplate the reinforcing
`nature of a nail tab to reduce nail head pullout or nail pull-
`through, is fatal to each of the three prior art combinations

`• “In moving to a contact process, there is the introduction of
`contamination from the substrate. If the substrate had any

`
`
`• “With proper weight attributed to my many years in the

`“Lassiter ‘409 Combined with Hefele Would Not Work.”
`Paper 16, pg. 28.
`
`
`
`• “Petitioner’s alleged combination of Lassiter and Hefele is
`riddled with problems. The first problem is that in an effort to
`find some motivation to combine Lassiter which uses asphalt
`coated substrates with Hefele’s non-asphalt substrate teachings
`(Ex. 1004, col. 2, line 63 – col. 3, line 4), Petitioner improperly
`asserts ‘that paper is a roofing or building cover material’
`which is wrong for all the reasons discussed previously.” Paper 16,
`pg. 29.

`
`“Lassiter ‘409 Combined with Hefele Would Not Work.”
`Paper 16, pg. 28.
`
`Ed Todd:
`
`
`“Hefele does not teach about adding reinforcement qualities to the sheet in
`order to enhance the burst strength, tear resistance or nail pull through as
`are needed in manufacturing a roof covering or underlayment product.” Ex.
`2003 ¶75.
`
`
`
`“The raster grid pattern precludes the addition of any useful
`reinforcement.” Ex. 2003 ¶76.

`
`“Lassiter ‘409 Combined with Hefele Would Not Work.”
`Paper 16, pg. 28.
`
`Dr. Mark Bohan:
`
`
`“The printing process described in Hefele produces a raster or punctiform.
`In addition, it is described that “[t]he grid-like coating can be punctiform,
`in bar form or in linear form” [Ex.1004 Col. 3:61-63]. These shapes are not
`complimentary to a nail tab and the reinforcement required for them.” Ex. 2004
`¶80.
`
`
`
`“This powdered deposit will not function as a nail tab because the pull-
`through reinforcing nature of nail tabs is incompatible with a structure
`made essentially of discontinuous powder.” Ex. 2004 ¶82.

`

`
`“The Hefele Device Will Not Function With A Heavily Asphalt
`Saturated Substrate.”
`Ex. 2004 ¶73.
`
`Ed Todd:
`
`
`“A heavily asphalt coated or saturated sheet is not a suitable substrate for
`the Hefele invention and will, in fact, render the Hefele methods and
`apparatus useless in short order.” Ex. 2003 ¶85.
`
`
`
`“I can think of no modifications to the Hefele invention that would allow it
`to be substituted into the Lassiter ‘409 invention and produce a working
`combination, much less a combination that could deposit nail tabs on a
`roofing or building cover material.” Ex. 2003 ¶86.

`

`
`“The Hefele Device Will Not Function With A Heavily Asphalt
`Saturated Substrate.”
`Ex. 2004 ¶73.
`
`Dr. Mark Bohan:
`
`
`“In all cases, the substrate materials described by Hefele are much more
`thermodynamically stable than saturated asphalt felt. In addition, those
`materials described by Hefele do not have oils on the surface of them
`which would contaminate the polymer being applied.” Ex. 2004 ¶75.
`
`
`
`“This contamination would migrate from the substrate to the heated roll 5,
`to the gravure roll 1 where it would disrupt the transfer of sintered powder
`agglomerates. This alone would cause the Hefele device to fail if an asphalt
`saturated substrate were used.” Ex. 2004 ¶77.

`
`

`
`“Hefele emphatically stated during prosecution that any
`modifications or deviations would be fatal to the transfer of the
`powder to the web. ”
`Paper 16, pg. 34.
`
`
`•
`
`“In fact if each individual part of the apparatus is not made to function as is
`claimed in Claim 1 the sum of the parts will not produce the desired novel
`result of transfer of adhesive powder to a web like material. Therefore it
`can be said that each limitation recited in Claim 1 is critical.” Ex. 2011, pg. 72.
`
`
`
`Ed Todd:
`
`
`“A person of ordinary skill would not be motivated to adjust, modify,
`substitute or change any part of the Hefele device after reading this
`passage.” Ex. 2003 ¶74.

`
`“Hefele Does Not Teach The Use Of Bonding Or Adhering
`Pressure.”
`Ex. 2004 ¶82.
`
`Dr. Mark Bohan:
`
`
`“Hefele teaches ‘slight’ pressure for ‘flattening’ the powder agglomerates to
`the substrate. This is different from ‘Bonding […] by pressure’ or ‘pressure
`adhering’ as required by claim 1 and 7 respectively in Collins ‘757 patent.”
`Ex. 2004 ¶83.
`
`
`
`“Hefele expressly teaches away from using a significant force, such as that
`used in the Collins ‘757 patent stating that ‘[t]oo great a flattening can be
`prevented by appropriate choice of a low application pressure of the roller.’
`[Ex. 1004, Col. 2: 45-46].” Ex. 2004 ¶84.

`“Hefele Does Not Teach The Use Of Bonding Or Adhering
`Pressure.”
`Ex. 2004 ¶82.
`
`Ed Todd:
`
`
`“Hefele does not teach pressure bonding or adhering as claimed in the ‘757
`patent because it teaches only slight pressure and expressly teaches how to
`avoid over flattening. [Ex. 1004, Col. 3:45-46].” Ex. 2003 ¶83.
`
`
`
`“In my opinion, the Hefele patent has no applicability to manufacturing
`roofing or building covering materials.” Ex. 2003 ¶83.

`“The Bayer Devices Cannot Produce A Nail Tab When Substituted in
`Lassiter.”
`Ex. 2004 ¶93.
`
`Dr. Mark Bohan:
`•
`“The Bayer device creates a coating by bringing an adhesive into contact
`with a substrate. This device is expressly directed to applying a thin layer
`of adhesive such as is used to make POST-IT brand repositionable notes.”
`Ex. 2004 ¶96.
`
`
`
`•
`
`•
`
`“The thickest adhesive layer disclosed by the Bayer device is 0.0014” thick
`or 1.4 mils. This is approximately seven times thinner than a traditional tin
`cap. The Bayer device, like the other references, is simply unable to deposit
`sufficient material to produce a nail tab.” Ex. 2004 ¶97.
`
`
`“The Bayer reference only discloses depositing ink and adhesives. At no
`point does it even remotely suggest depositing a polymer with the intrinsic
`reinforcing properties necessary to make a nail tab.” Ex. 2004 ¶97.

`
`
`“Bayer’s device is centered on applying adhesive and does not disclose any
`reinforcing properties.” Ex. 2003 ¶109.
`
`
