The latest of international trade deals, the TPP, signed October 5^th, 2015, produced about seven pages of patent provisions that, under Canadian law, leave little impact. The Federal government’s is that Canadian law is already in compliance with these provisions. While this might be true, a more objective analysis of the text could support the argument that the TPP does in fact require some legal reform. However, legal reform would not create new legal obligations, as Canada has already committed to that reform under the newly minted Comprehensive Economic and Trade Agreement ()

Of all the TPP’s patent provisions, three concerning pharmaceutical drug patents are most notable. The first is patent term restoration, which extends patent terms in response to administrative delays. And the third is extended data protection specifically for biologics, a new form of prescription drug.

The first of the TPP’s notable provisions, concerning patent term restoration, can be found in articles and . Both provisions offer patent extensions in response to administrative delays. Article 18.46 grants extensions for patent office delays, and extends pharmaceutical patent terms by a time equal to any “unreasonable” delay in a drug's regulatory approval. Article 18.48 is not currently found in Canadian law, nor under .

The purpose of the provision is to recognize that patent enabled drug monopolies are of little value when drugs cannot be legally sold. This is welcome news for those who believe current patent terms successfully , as lost monopoly time would hinder pharmaceutical development. Also, everyone can appreciate how the provision detaches patent terms from flexible regulatory approval processes, adding certainty to IP investments and assurances against regulatory favouritism. Yet some argue term restoration is a tool for IP owners, used to extend an already sufficient monopoly.

The second notable provision is article , patent linkage. of patent linkage argue that tying marketing approval to previous patents creates space for tactical litigation, which can be used to delay generic competition and, in effect, extend patent terms. Although this was a debated topic during and after TPP negotiations, Canada has already employed for some time, and has also committed to linkage rules similar to the TPP since signing CETA.

The last of the TPP’s notable provisions can be found in articles and , which offer . This type of research is necessary for marketing approval and is an expensive cost of drug development. Supporters of data protection argue these provisions shield drug developers from free-riders, thus incentivizing invention. Though opponents might take issue with adding protecting of information on top of invention.

However, these provisions do not create monopolies on information, the way patents create monopolies on invention. Generic companies are free to rely on the same safety and efficacy data as the patent owners, so long as it is reproduced at their own expense.

The TPP grants a five-year protection on drug efficacy and safety data, and an additional three-year protection on research concerning biologic drugs, so-called large molecule drugs. Biologics are an emerging field of pharmaceuticals, and the extended protection is meant to recognize the often high risk and cost associated with exploratory research.

However, some suggests that a longer term of twelve years would be ideal, even considering this advantage. The TPP's compromise is eight years, which reflects Canada's current .

It is difficult to determine whether the provisions presented in the TPP’s patent chapter will help or harm Canadian interests. This determination will depend in no small part on which perspective the analysis is based. The TPP’s patent provisions are likely not immediately useful for consumers of patented drugs. Patent term restoration, patent linkage, and data protection all serve to strengthen patents.

However, these are welcome provisions from the perspective of drug developers, as they increase the value of existing and new patents. In this sense, perhaps the rules are also good for Canada. For example, biologics were given special protection to encourage investment. Canada’s pharmaceutical research and development sector, one of its largest, would likely benefit from this improvement in market conditions, especially since investment in that sector has recently suffered steady .

�ճ���� IP chapter includes several rules that indirectly extend patent terms for pharmaceutical drugs, such as ,��, and . However, the actual benefit these provisions provide is 

Take patent term restoration for example, which extends patent terms by a time equal to any “unreasonable” delay in a drug's regulatory approval. This provision's purpose recognizes that patent enabled drug monopolies are of little value when drugs cannot be sold legally. And the TPP considers any five-year delay unreasonable.

Patent restoration is welcome news for those who believe current patent terms successfully ,��because lost monopoly time would hinder pharmaceutical development. This provision also detaches patent terms from flexible regulatory approval processes, adding certainty to IP investments. And it adds assurances against regulatory favouritism. However, some critics argue term restoration is a tool for IP owners used to extend an already sufficient monopoly.

Another debated policy found in the TPP is patent linkage. This rule requires generic drug companies to prove their products do not infringe any existing patents before they can be granted marketing approval.  of patent linkage believe tying marketing approval to previous patents creates space for tactical litigation that can be used to delay generic competition and in effect extend patent terms. However, Canada already employs patent linkage, and has already committed to linkage rules similar to the TPP by signing .

In addition to patent restoration and patent linkage, the TPP includes two controversial pro-patent provisions that provide data protection to pharmaceutical efficacy and safety research. This research is necessary for marketing approval and is an expensive cost of drug development. Supporters of the data provisions argue that these protections incentivize invention by shielding drug developers from free-riders.

Opponents of these provisions might take issue with protecting information on top of invention. However,��this is not a monopoly on information, and generic companies are free to use the same data so long as it is reproduce at their own expense.

The TTP grants five year's protection on drug efficacy and safety data, and an additional three year's protection to research concerning biologic drugs, so called large molecule drugs. Biologics are an emerging field of pharmaceuticals, and the extended protection is meant to recognize how exploratory research is often more risky and thus more expensive.

One compelling  against special protection concerns the nature of biologic drugs. Whereas traditional small molecule drugs are chemically synthesized and easily reproduced, biologics often have genetic and cellular components that are not as simple, or cheap, to replicate. Critics think this creates a natural barrier to entry, giving biologic developers a first-mover advantage that sufficiently returns the risky cost of research, eliminating any need for data protection.

However,��some  suggests, even considering this advantage,��that a longer term of twelve years would be ideal. The TPP's compromise is eight years, which reflects Canada's current .

As is usually the case with trade deals, the TPP’s patent provisions fall short of both advocates' highest hopes and critics' worst fears. For Canadian law, the TPP will have little effect. But this is not necessarily a good thing. Current patent rules may not be best for incentivizing drug development, as the  over patent policy suggests. Meaning,��this failure to change might successfully impede innovation.

All that can be said with certainty is the TPP will not reduce the price of today's life-saving drugs. Whether innovation properly compensates this cost is for posterity to judge.
