The Abbott Applications teach that a certain level of muscle function is necessary for mobility and carrying out activities of daily living. A decline in muscle function can have a number of adverse effects on an individual including, but not limited to, general weakness, fatigue, a lessening of joint mobility, a reduction in physical activities…, see paragraph 0003 of the ‘457 application.
Also, the Abbott Applications teach that extended bed rest or physical inactivity may lead to a number of complications such as low-grade inflammation (Hojbjerre, L., et al., Diabetes Care 34(10): 2265-2272, 2011), cardiovascular complications (Sonne, M. P., et al., Exp Physiol 96(10): 1000-1009, 2011), rapid muscle atrophy, and degenerative joint disease (Dittmer, D. K., et al., Can Fam Physician 39: 1428-1432, 1435-1437, 1993). Such complications may be related to the development of fibrosis in tissue due to dysregulated matrix metalloproteinase (MMP) activity. The development of fibrosis may in turn lead to the development of other conditions or complications such as arthritis, atherosclerosis, nephritis, tissue ulcers, aneurysms, and muscle atrophy, see paragraph 0003 of the ‘350 application.
In order to reduce fibrosis, increase muscle regeneration and decrease muscle function decline, the Abbott Applications teach the administration of compositions comprising HMB (“[a]lso provided is a method of reducing the effect of prolonged physical inactivity on the development of fibrosis in a subject who is experiencing or is expected to experience prolonged physical inactivity in the near future by administering a therapeutically effective amount of a leucine metabolite (e.g., β-hydroxy-β-methylbutyric acid (HMB)) to the subject….[c]ompositions and methods for enhancing the regenerative capacity of an individual are provided. The compositions include, and the methods provide, a combination of an effective amount of epigallocatechin-3-gallate (EGCg) and an effective amount of β-hydroxy-β-methylbutyrate (HMB) to decrease the level of intramuscular FGF2, to enhance the regenerative capacity of muscle, or both.”).
The Abbott Applications clearly demonstrate the relationship between muscle and joint health, namely, a decline in muscle function can have a number of adverse effects on joint mobility and joint health. Within this context, the Abbott Applications teach that compositions comprising HMB can increase muscle regeneration, decrease fibrosis and decrease muscle decline, and invariably, benefits joint health.
In this relationship, see also Rathmacher (“A method for increasing muscle mass of an animal in need thereof comprising the steps of administering to said animal HMB and Vitamin D in amounts sufficient to increase muscle mass, wherein upon said administration of HMB and Vitamin D to the animal, said muscle mass is increased”, see claim 20.)
WO 696 also teaches administration of HMB and vitamin D to increase muscle mass strength and functionality, see abstract, for example.
The primary references may not teach improving joint stability or treating joint inflammation, joint damage, and/or joint injury. However, the secondary references teach that muscle mass and muscle contractions are essential to maintain functional joints. The loss of muscle mass can lead to joint instability and affect the joint function, which may then lead to inflammation and eventually arthritis. See Applicant’s remarks dated 8/17/2019 in a reply filed in parent application 15/405,880, citing the Knoop references and Messier:

See Remarks dated 8/27/2019, 15/405,880, pp. 6-7.
In this manner, increasing muscle mass with HMB necessarily improves joint instability and joint function, as admitted by Applicant.
Nonetheless, CN 247 teaches a parental drink for relieving joint chronic strain comprising B- hydroxy-B methylbutyric acid calcium, see example 8 of Machine Translation, previously provided.
In this way, those of ordinary skill could have applied the HMB compositions taught by the primary references in a predictable fashion for the purposes of improving joint health. Specifically, the references teach that the particular known technique of improving muscle health with HMB was within the ordinary capabilities of those of ordinary skill. Since the references also demonstrate that muscle and joint health are recognized as invariably interconnected, those of ordinary skill would have recognized that applying the known technique would have yielded a reasonable expectation of improving joint health. Accordingly, applying HMB compositions for improving joint health would have been prima facie obvious.
The claims have been amended to recite increasing muscle mass in the limb contralateral to the effected joint, thereby improving neuromuscular balance and joint stability. The claims also recite increasing strength in a limb contralateral to the affected joint, thereby compensating for the joint instability caused by the joint inflammation, joint damage, and/or joint injury.
Again, those of ordinary skill would recognize that administration of HMB, as taught by the references, would necessarily increase muscle mass and strength in the limb contralateral to the effected joint, see MPEP 2112.01 (“Products of identical chemical composition can not have mutually exclusive properties.” In re Spada, 911 F.2d 705, 709, 15 USPQ2d 1655, 1658 (Fed. Cir. 1990). A chemical composition and its properties are inseparable. Therefore, if the prior art teaches the identical chemical structure, the properties applicant discloses and/or claims are necessarily present.”). See also In re Woodruff "discovering and claiming a new benefit of an old process cannot render the process again patentable." 919 F. 2d 1575, 1578 (Fed. Cir. 1990).
As mentioned previously, Applicant Remarks dated 8/27/2019, 15/405,880, pp. 6-7, describe how increasing muscle mass with HMB necessarily improves joint instability and joint function, which was as admitted by Applicant.
As outlined above, with regard to improving increasing contralateral muscle mass and strength, those of ordinary skill would recognize that administration of HMB, as taught by the references, would necessarily improve balanced movement and increase muscle mass and strength, including increasing muscle mass in the side of the body contralateral to the site of joint inflammation, damage and injury. Any other observed effect, such as improved balanced movement, would also be a necessary aspect of HMB administration.
Applicant argues that:
Not all administration of HMB results in contralateral effects;
Not all contralateral muscle gain translates to joint stabilization;
Not one cited reference teaches or predicts the contralateral stabilization mechanism; and
Contralateral strength targeting is a purposeful therapeutic strategy, not an inevitable outcome.
However, the references teach a decline in muscle function can have a number of adverse effects on an individual including a lessening of joint mobility and that increasing muscle mass can be achieved by administering HMB. In this manner, the references provide a reason to administer HMB to those with joint instability and injury. Any other observed effects, such as those mentioned by applicant, or recited in the claims, would have been an invariable aspect of this administration.
Moreover, the claims do not recite any differences in the manner of administration of HMB from that disclosed in the references which would translate into differences in contralateral effects or joint stabilization.
Therefore, the rejection is maintained.
THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
