`For Appellant
`
`EXAMINER’S ANSWER
`
`This is in response to the appeal brief filed 22 February 2017 appealing from the
`
`Office action mailed 30 June 2016.

`
`(1) Grounds of Rejection to be Reviewed on Appeal
`
`Every ground of rejection set forth in the Office action dated 30 June 2016 from
`
`which the appeal is taken is being maintained by the examiner except for the grounds of
`
`rejection (if any) listed under the subheading “WITHDRAWN REJECTIONS.” New
`
`grounds of rejection (if any) are provided under the subheading “NEW GROUNDS OF
`
`REJECTION.”
`
`(2) Response to Argument
`
`Claims 1, 2, 4, 5, 7, 8 and 10-12 are rejected under 35 U.S.C. 103(a) as being
`
`unpatentable over Herbert (US 20100291664) in view of Cox (US 3907389) and
`
`Barbera-Guillem (US 20030040104).
`
`Appellant’s principal arguments are
`
`(a) Barbera-Guillem teaches an environmental controlling mechanism in a culture
`
`apparatus, which corresponds to the claimed working chamber (and not the storage
`
`chamber). Accordingly, there would be no reason to add an environmental controlling
`
`mechanism to the storage chamber of Herbert (pages 10-11).
`
`In response, please consider the following.
`
`Appellant is wrong to suggest that the chamber 14 of Barbera-Guillem does not
`
`correspond to the claimed storage chamber because the chamber 14 taught by
`
`Barbera-Guillem i_s a storage chamber. Paragraphs [0010], [0038]-[0044] and [0048]
`
`repeatedly describe the chamber 14 as containing a storage array 20. The storage
`
`array is used to store cell culture containers 22. Because the storage array 20 stores
`
`
`
`Application/Control Number: 13/457,675
`
`Page 3
`
`Art Unit: 1799
`
`the containers in the chamber 14, chamber 14 is considered to be a storage chamber.
`
`Although Barbera-Guillem also describes the containers 22 as culture containers, the
`
`culture containers are stored in the storage array 20 within the storage chamber 14.
`
`The storage chamber 14 allows cells to be stored during culture, wherein “culture”
`
`simply means that the cells are allowed to grow on the container surfaces while they are
`
`being stored.
`
`The storage chamber 14 of Barbera-Guillem therefore naturally corresponds to
`
`the storage chamber 2 of Herbert.
`
`In view of Barbera-Guillem, one of ordinary skill
`
`would have been motivated to include an environment controlling mechanism in the
`
`storage chamber 2 of Herbert when the Herbert storage chamber is used to store cells
`
`for cell culture or any other temperature material. As evidenced by Barbera-Guillem,
`
`environment controlling mechanisms, such as heaters/coolers, can affect the conditions
`
`within a sealed room in a highly predictable way. Barbera-Guillem further teaches that it
`
`is appropriate to keep viable cells at desirable temperatures at all times, as it is common
`
`knowledge that different cells grow best at different temperatures.
`
`(b) There are key differences between culture chambers and storage chambers,
`
`and it would not have been obvious to provide a temperature control device to a storage
`
`chamber. There is no reason to apply a temperature control device to the storage
`
`chamber of Herbert (page 1 1).
`
`In response, please consider the following.
`
`
`
`Application/Control Number: 13/457,675
`
`Page 4
`
`Art Unit: 1799
`
`For the reasons expressed above, the chamber 14 of Barbera-Guillem is a
`
`storage chamber.
`
`It stores culture containers. The fact that cells are allowed to grow
`
`(and are not intentionally killed) in the Barbera-Guillem chamber 14 does not defeat the
`
`
`fact that the chamber 14 holds, retains and stores the containers. Because Barbera-
`
`Guillem clearly teaches the value of a temperature controlled storage chamber, one of
`
`ordinary skill would have also considered making other similar storage chambers, such
`
`as the storage chamber of Herbert, temperature controlled for the same reasons.
`
`Even if, for the sake of argument, Appellant is correct that there is no rigid,
`
`cookie-cutter type teaching-suggestion-motivation statement indicating why a
`
`temperature adjusting device should be added to the Herbert storage chamber, it is
`
`emphasized that adding a heater or a cooling element to the Herbert storage chamber
`
`merely represents combining prior art elements according to known methods to yield
`
`predictable results, which is prima facie obvious. See MPEP 2143. Heating elements
`
`(which are generally taught by all of Herbert, Cox and Barbera-Guillem) are well known
`
`in the art and are characterized by a predictable operation. A heating/cooling means
`
`added to the storage chamber of Herbert would operate in exactly the same way as it
`
`would in essentially any other type of chamber (“The rationale to support a conclusion
`
`that the claim would have been obvious is that all the claimed elements were known in
`
`the prior art and one skilled in the art could have combined the elements as claimed by
`
`known methods with no change in their respective functions”).
`
`
`
`Application/Control Number: 13/457,675

`
`Art Unit: 1799
`
`(c) The present disclosure is based on the idea of temporarily storing culture in a
`
`space in which culture is not stored conventionally. As a result, temperature in the
`
`storage chamber is adjusted to protect culture from changes in the environment (page
`
`12).
`
`In response, please consider the following.
`
`The storage chamber of Herbert also temporarily stores culture containers. The
`
`storage chamber is a hatch that holds material as it moves from one chamber to
`
`another.
`
`It can be used to hold a culture container for essentially any period of time.
`
`It
`
`would make sense, especially in view of Barbera-Guillem, to subject biological cells to
`
`appropriate temperatures at all times wherever they are located, including in all storage
`
`locations. One of ordinary skill would not have wanted growing cells to be in conditions
`
`that are too hot or too cold, even for short periods of time.
`
`Appellant’s argument essentially boils down to the assertion that the claimed
`
`storage chamber holds culture containers for a longer period of time than the Herbert
`
`storage chamber. However, this is a question of intended use. A recitation of the
`
`intended use of the claimed invention (here, the amount of time a culture container
`
`resides within the storage space) must result in a structural difference between the
`
`claimed invention and the prior art in order to patentably distinguish the claimed
`
`invention from the prior art.
`
`If the prior art structure is capable of performing the
`
`intended use, then it meets the claim.
`
`In this case, the Herbert storage chamber is
`
`structurally capable of holding a cell culture container for essentially any period of time.

`
`Art Unit: 1799
`
`(d) With respect to claims 1 1 and 12, the claimed method involves adjusting the
`
`temperature of the culture stored in the working chamber when culture taken out of the
`
`culture chamber has been stored in the working chamber and the working chamber has
`
`been hermetically sealed. Based on Barbera-Guillem, one of ordinary skill in the art
`
`would have no reason to modify Herbert such that the temperature of either of the
`
`isolation cabinets 3, 6, 9, 11 and 13 is controlled or the temperature of the transfer
`
`hatch 2 (regarded as a "storage chamber’Q is controlled (pages 13 and 14).
`
`In response, please consider the following.
`
`Again, one of ordinary skill would have found it obvious to control the
`
`temperature of any room, including storage chambers, where biological cells are
`
`located. Barbera-Guillem shows one such storage chamber that includes a temperature
`
`control element. A heater/cooler added to the Herbert storage chambers 2, 17 would
`
`allow cells to remain at temperatures appropriate for cell growth while they reside within
`
`the storage chamber. Furthermore, a heater/cooler added to the Herbert storage
`
`chambers 2, 17 would keep the storage chamber and the working chamber at
`
`approximately the same temperature, which would prevent too hot or too cold air from
`
`entering into the working chamber when the door between the storage chamber and the
`
`working chamber is opened. A heater/cooler added to the Herbert storage chambers 2,
`
`17 could also function as a "back-up" emergency temperature control means in the
`
`event that the heating/cooling system in the working chamber became inoperative and
`
`cell culture containers needed to be moved into the storage chamber.

`
`Claims 1, 2, 4, 5, 7, 8 and 10-12 are rejected under 35 U.S.C. 103(a) as being
`
`unpatentable over Cox (US 3907389) in view of Barbera-Guillem (US
`
`20030040104).
`
`Appellant’s arguments are essentially the same as those presented above (i.e.
`
`regarding the Barbera-Guillem teachings and that there would be no reason to add an
`
`environmental controlling mechanism to the storage chamber of an isolator
`
`(environmental chamber)). Because these arguments are not persuasive, the rejections
`
`involving the combination of Cox with Barbera-Guillem should be sustained.
`
`For the above reasons, it is believed that the rejections should be sustained.
