It is the administrative paper trail. While the industry fixates on patent term extensions, a more quiet and effective strategy is unfolding in the filing offices of the European Patent Office (EPO). Originator companies use a mechanism known as the divisional patent to maintain a permanent state of legal uncertainty. They file a continuous stream of overlapping applications, often with no expectation that these filings will survive a full legal challenge. The goal is to prevent a final decision from ever appearing on the record.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Administrative Loophole That Never Closes<\/strong><\/h2>\n\n\n\n<p>The legal architecture of the European patent system allows an applicant to split a pending patent application into separate filings. These are called divisional applications. Under Article 76 of the European Patent Convention (EPC), a divisional application retains the filing and priority dates of its parent.<sup>1<\/sup> This means it is protected from any evidence or publications that appeared after the original filing years earlier.<sup>2<\/sup> In theory, this helps inventors separate multiple inventions found within one broad application. In practice, it allows a company to keep a patent family alive for the entire 20-year term of the original patent.<sup>3<\/sup><\/p>\n\n\n\n<p>Current rules under Rule 36(1) EPC state that an applicant can file a divisional for any pending earlier application.<sup>1<\/sup> An application remains pending until the date the European Patent Bulletin mentions the grant, or until the time to appeal a refusal expires.<sup>1<\/sup> By ensuring that at least one branch of a patent family is always in prosecution, a company can ensure that the legal status of its product is never fully settled.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Feature<\/strong><\/td><td><strong>European Divisional Application<\/strong><\/td><\/tr><tr><td>Legal Basis<\/td><td>Article 76 EPC and Rule 36 EPC <sup>1<\/sup><\/td><\/tr><tr><td>Priority Date<\/td><td>Inherited from the parent application <sup>2<\/sup><\/td><\/tr><tr><td>Filing Limit<\/td><td>Any time while the parent application is pending <sup>4<\/sup><\/td><\/tr><tr><td>Geographical Scope<\/td><td>Limited to the states designated in the parent <sup>2<\/sup><\/td><\/tr><tr><td>Examination<\/td><td>Independent of the parent application <sup>5<\/sup><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>This system creates a &#8220;Whack-A-Mole&#8221; scenario for generic and biosimilar manufacturers. Every time a competitor successfully challenges a patent in an EPO opposition proceeding, the originator can activate a pending divisional. These proceedings typically take three to six years to reach a final resolution at the Technical Board of Appeal.<sup>6<\/sup> By the time one patent is revoked, another is granted or pending, restarting the clock for the challenger.<sup>3<\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Mechanics of Pendency under Article 76<\/strong><\/h2>\n\n\n\n<p>The definition of &#8220;pending&#8221; is the heart of the divisional strategy. If the EPO refuses an application, it remains pending until the appeal period expires.<sup>1<\/sup> If the applicant files an appeal, the application stays pending until the Board of Appeal issues a final decision. During this entire time, the applicant can file new divisionals based on the same disclosure.<sup>3<\/sup><\/p>\n\n\n\n<p>Companies often file these divisionals when a parent case is &#8220;cruising towards refusal,&#8221; such as before oral proceedings where success is unlikely.<sup>5<\/sup> Filing a divisional offers an opportunity to reset and reframe the strategy.<sup>5<\/sup> This creates &#8220;zombie&#8221; applications that haunt the market, even when the underlying scientific claims have been rejected.<sup>7<\/sup><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Rule<\/strong><\/td><td><strong>Requirement<\/strong><\/td><td><strong>Strategic Impact<\/strong><\/td><\/tr><tr><td>Rule 36(1)<\/td><td>Application must be pending<\/td><td>Allows for &#8220;back-up&#8221; filings if a refusal is imminent.<sup>8<\/sup><\/td><\/tr><tr><td>Rule 36(2)<\/td><td>Language of the earlier application<\/td><td>Maintains consistency across the family.<sup>1<\/sup><\/td><\/tr><tr><td>Rule 36(3)<\/td><td>Fees due within one month<\/td><td>Small cost relative to the value of market exclusivity.<sup>1<\/sup><\/td><\/tr><tr><td>Rule 38(4)<\/td><td>Additional fee for subsequent generations<\/td><td>Intended to deter excessive filing, but often ineffective for blockbusters.<sup>1<\/sup><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Teva and the Architecture of Abuse<\/strong><\/h2>\n\n\n\n<p>The European Commission recently provided a clear signal that this behavior has limits. On October 31, 2024, the Commission fined Teva \u20ac462.6 million for abusing its dominant position related to Copaxone, a drug used for multiple sclerosis.<sup>9<\/sup> The investigation focused on Teva\u2019s use of glatiramer acetate, the active ingredient in Copaxone.<sup>9<\/sup><\/p>\n\n\n\n<p>The Commission found that Teva engaged in a &#8220;divisional game.&#8221; As the original patent for glatiramer acetate neared its 2015 expiration, Teva filed multiple divisional applications in a staggered way.<sup>9<\/sup> These secondary patents focused on manufacturing processes and dosing schedules.<sup>9<\/sup> This created a web of overlapping protection that rivals had to clear before entering the market.<sup>9<\/sup><\/p>\n\n\n\n<p>The Commission\u2019s finding centered on how Teva enforced these patents. Teva obtained interim injunctions against competitors based on these divisional patents while they were still under review by the EPO.<sup>9<\/sup> When it appeared that the EPO was likely to revoke a patent, Teva strategically withdrew it.<sup>9<\/sup> This prevented a formal invalidity ruling that would have set a precedent and threatened the rest of the divisional family.<sup>9<\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Staggered Filings and the Withdrawal Tactic<\/strong><\/h2>\n\n\n\n<p>The Teva case shows that the goal of a divisional is often not to secure a permanent patent, but to secure time. By staggering the filings, Teva ensured that its competitors were stuck in a loop of litigation for nine years, from 2015 to 2024.<sup>11<\/sup> Every time a competitor won a challenge, they were met with a new patent or a withdrawal that erased the legal victory.<sup>9<\/sup><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Teva&#8217;s Patent Web<\/strong><\/td><td><strong>Member States Affected<\/strong><\/td><td><strong>Duration of Infringement<\/strong><\/td><\/tr><tr><td>Glatiramer Acetate<\/td><td>Belgium, Czechia, Germany, Italy, Netherlands, Poland, Spain <sup>9<\/sup><\/td><td>4 to 9 years depending on the country <sup>12<\/sup><\/td><\/tr><tr><td>Focus Areas<\/td><td>Manufacturing process and dosing regimen <sup>9<\/sup><\/td><td>Until all patents were finally annulled <sup>9<\/sup><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>This strategy was supplemented by a disparagement campaign. Teva spread misleading information about a competing product&#8217;s safety and efficacy, targeting doctors and health officials.<sup>9<\/sup> Even though health authorities had approved the rival drug, Teva&#8217;s campaign created enough doubt to slow its market uptake.<sup>9<\/sup> The Commission concluded that these two tactics\u2014the misuse of divisionals and the disparagement campaign\u2014were a single, continuous infringement of Article 102 of the TFEU.<sup>9<\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Economics of Legal Uncertainty<\/strong><\/h2>\n\n\n\n<p>Legal uncertainty is a financial asset for originator firms and a liability for generic manufacturers. When a drug loses its primary patent, its price usually drops to a fraction of the original within 12 months.<sup>13<\/sup> In a competitive generic market, the price often settles at 6% to 20% of the branded price.<sup>13<\/sup> By delaying this drop for even a few years, a company can preserve billions in revenue.<\/p>\n\n\n\n<p>For generic companies, the risk of an &#8220;at-risk&#8221; launch is high. If they launch while a divisional patent is pending and that patent later grants and is upheld, they face massive damages and injunctions.<sup>14<\/sup> The divisional strategy exploits this risk aversion. It forces competitors to choose between expensive, multi-year litigation or waiting until every possible patent is cleared.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Stakeholder<\/strong><\/td><td><strong>Financial Risk from Patent Challenges<\/strong><\/td><td><strong>Average Value at Stake<\/strong><\/td><\/tr><tr><td>Brand-Name Firm<\/td><td>Loss of market exclusivity and revenue cliff <sup>14<\/sup><\/td><td>$4.3 billion in market cap <sup>14<\/sup><\/td><\/tr><tr><td>Generic Firm<\/td><td>Wasted R&amp;D and legal fees if they lose <sup>14<\/sup><\/td><td>$204.3 million in market cap <sup>14<\/sup><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Institutional investors use platforms like DrugPatentWatch to model these outcomes. A pharmaceutical patent estate is a layered position consisting of primary compound patents, formulations, and methods of use.<sup>16<\/sup> Each layer has a different survival probability.<sup>16<\/sup> A primary patent might have a 90% survival probability, while a weak dosing divisional might only have 20%.<sup>16<\/sup> However, as long as that 20% probability exists, it can block entry.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Revenue at Risk and the Patent Cliff<\/strong><\/h2>\n\n\n\n<p>Between 2025 and 2030, the pharmaceutical industry faces a &#8220;patent cliff&#8221; where drugs generating over $200 billion in annual sales will lose exclusivity.<sup>14<\/sup> This is one of the largest transfers of wealth in industrial history.<sup>15<\/sup> The timing of these cliffs is often determined by the outcome of Paragraph IV challenges in the US or opposition proceedings in Europe.<sup>14<\/sup><\/p>\n\n\n\n<p>DrugPatentWatch tracks these events across 134 countries.<sup>17<\/sup> This global view is necessary because a patent strategy in the US often diverges from Europe. In the US, companies use &#8220;terminal disclaimers&#8221; to link patents together.<sup>19<\/sup> In Europe, they use cascading divisionals. A company might have a strong position in the US but be vulnerable in Europe, where biosimilars often launch years earlier.<sup>18<\/sup><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Drug Name<\/strong><\/td><td><strong>US Launch of Competition<\/strong><\/td><td><strong>EU Launch of Competition<\/strong><\/td><td><strong>Gap (Years)<\/strong><\/td><\/tr><tr><td>Humira<\/td><td>2023<\/td><td>2018<\/td><td>5.0 <sup>20<\/sup><\/td><\/tr><tr><td>Enbrel<\/td><td>Expected 2026+<\/td><td>2016<\/td><td>10.0+ <sup>20<\/sup><\/td><\/tr><tr><td>Eliquis<\/td><td>Expected 2026+<\/td><td>2022<\/td><td>4.0+ <sup>20<\/sup><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>This gap represents a massive difference in spending. For just three drugs\u2014Humira, Eliquis, and Enbrel\u2014Americans will spend an estimated $167 billion on branded versions during the years when Europe already had access to cheaper generics and biosimilars.<sup>20<\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Case Study: The Adalimumab Wall<\/strong><\/h2>\n\n\n\n<p>AbbVie\u2019s Humira (adalimumab) is the definitive case study for patent thickets. In the United States, AbbVie secured over 130 patents for Humira, creating a wall that kept biosimilars out until 2023.<sup>21<\/sup> Most of these patents were filed after the drug was already approved in 2002.<sup>21<\/sup> These patents did not reflect new innovations but were part of a strategic marketing defense.<sup>21<\/sup><\/p>\n\n\n\n<p>In Europe, the strategy was different because the EPO system is more predictable and less susceptible to the type of thicket seen in the US.<sup>23<\/sup> However, AbbVie still used secondary patents and divisionals to manage its lifecycle. When biosimilars finally entered the European market in 2018, the price of Humira dropped by 90% in some regions, such as the Netherlands.<sup>21<\/sup> This drop proved that the high price was purely a result of the monopoly position, not the cost of innovation.<sup>21<\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Comparing US Thickets and European Cascades<\/strong><\/h2>\n\n\n\n<p>The US and European systems handle &#8220;double patenting&#8221; differently. The US allows companies to obtain obvious variants of their own inventions through terminal disclaimers.<sup>19<\/sup> This means the patents expire at the same time as the original, but they still serve as independent legal hurdles that a competitor must litigate.<sup>19<\/sup><\/p>\n\n\n\n<p>The EPO strictly prohibits double patenting.<sup>24<\/sup> It does not permit terminal disclaimers and requires that claims in related applications be distinct.<sup>24<\/sup> While this seems like it would prevent thickets, companies get around this by using &#8220;salami-slicing&#8221;.<sup>3<\/sup> They take a broad invention and carve it into many small, narrowly defined patents. One divisional might claim a specific dose, another a specific manufacturing temperature, and a third a specific patient sub-group.<sup>9<\/sup><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Strategy Component<\/strong><\/td><td><strong>US Patent Thicket (e.g., Humira)<\/strong><\/td><td><strong>European Divisional Cascade (e.g., Copaxone)<\/strong><\/td><\/tr><tr><td>Primary Mechanism<\/td><td>Terminal Disclaimers <sup>19<\/sup><\/td><td>Cascading Rule 36 Filings <sup>3<\/sup><\/td><\/tr><tr><td>Number of Patents<\/td><td>Often 100+ <sup>22<\/sup><\/td><td>Typically 5-15 in a core family <sup>25<\/sup><\/td><\/tr><tr><td>Focus<\/td><td>Obvious variants of the same product <sup>24<\/sup><\/td><td>Narrowing the claim scope to &#8220;salami-slice&#8221; <sup>3<\/sup><\/td><\/tr><tr><td>Legal Risk<\/td><td>High cost of challenging 100+ patents <sup>19<\/sup><\/td><td>Extended uncertainty due to pendency <sup>6<\/sup><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Rise of the Unified Patent Court<\/strong><\/h2>\n\n\n\n<p>The launch of the Unified Patent Court (UPC) in June 2023 changed the calculation for divisional strategy. The UPC has jurisdiction over Unitary Patents and classic European Patents across 18 Member States.<sup>27<\/sup> It provides a single forum for both infringement and revocation actions.<sup>27<\/sup> During its first year, the UPC received 373 cases, 134 of which were infringement actions.<sup>28<\/sup><\/p>\n\n\n\n<p>The UPC is designed to be faster than national courts, with first-instance decisions expected in 12 to 14 months.<sup>28<\/sup> For generic firms, this could be a way to clear an entire patent family in one action.<sup>27<\/sup> However, originators are using divisionals to stay outside the UPC\u2019s reach. They can &#8220;opt out&#8221; classic European patents from the UPC\u2019s jurisdiction, forcing competitors to litigate in individual national courts.<sup>27<\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Tactical Bifurcation and Forum Shopping<\/strong><\/h2>\n\n\n\n<p>Originators often use a hybrid strategy. They may validate a parent patent as a Unitary Patent (subject to the UPC) while keeping a divisional application as a classic bundle patent that they opt out.<sup>5<\/sup> This allows them to choose the venue that is most favorable to their case. If the UPC appears to be leaning toward revocation, they still have their opted-out national patents as a fallback.<sup>5<\/sup><\/p>\n\n\n\n<p>The UPC has established a &#8220;No Stay&#8221; presumption.<sup>29<\/sup> This means that the court will generally not pause its proceedings just because an opposition is pending at the EPO.<sup>29<\/sup> In <em>Carrier Corp. v. Vicot<\/em>, the UPC Court of Appeal refused to stay a revocation action, emphasizing that the UPC has a mandate to adjudicate regardless of parallel EPO proceedings.<sup>29<\/sup> This could limit the effectiveness of the divisional game by providing a final decision on validity much faster than the EPO\u2019s appeal process.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>UPC Case Metrics (Year 1)<\/strong><\/td><td><strong>Data Point<\/strong><\/td><\/tr><tr><td>Total Cases Received<\/td><td>373 <sup>28<\/sup><\/td><\/tr><tr><td>Infringement Actions<\/td><td>134 <sup>28<\/sup><\/td><\/tr><tr><td>Member States Participating<\/td><td>18 <sup>27<\/sup><\/td><\/tr><tr><td>Expected Time to Decision<\/td><td>12-14 Months <sup>28<\/sup><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Technical Layering: Salami-Slicing Inventions<\/strong><\/h2>\n\n\n\n<p>The &#8220;salami-slicing&#8221; strategy is most common in biologics and complex small molecules. A biologic drug is not just a chemical formula; it is a product of a specific cell line and a precise manufacturing process.<sup>16<\/sup> Originators file divisionals covering the specific glycosylation profile, the purification sequence, and the dosing regimen.<sup>16<\/sup><\/p>\n\n\n\n<p>In the case of erythropoietin (EPO), litigation in the 1980s and 1990s established a precedent for &#8220;salami-slicing&#8221; recombinant DNA claims.<sup>30<\/sup> The courts allowed companies to secure patents for incremental improvements, which narrowed the research focus of the entire sector.<sup>30<\/sup> This has now evolved into the &#8220;divisional game&#8221; where every minor variation in a manufacturing step is used to file a new application.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Dosing Regimens as Defensive Moats<\/strong><\/h2>\n\n\n\n<p>Method-of-use (MoU) patents are a favorite tool for divisional cascades.

The Teva fine shows that the European Commission will use antitrust law to fill the gaps in patent regulation. Originator firms can no longer rely on the complexity of the EPO administrative process to block competition without facing the risk of massive fines. For the generic industry, the rise of the UPC provides a potential fast track to clear patent thickets that once took decades to litigate. Success in this new environment requires moving away from reactive legal defense and toward proactive institutional intelligence. By using tools like DrugPatentWatch to map the layered defense of blockbusters, companies can identify the cracks in the divisional wall and time their market entry with surgical precision. The divisional game is not over, but the rules are finally being enforced.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Key Takeaways<\/strong><\/h2>\n\n\n\n<p>The European patent landscape is dominated by the strategic use of divisional applications to maintain legal uncertainty. Companies like Teva have shown that staggering these filings and withdrawing them before a decision can delay generic entry for nearly a decade. While the EPO is introducing generation-specific fees in 2026, the real deterrent is the European Commission&#8217;s willingness to levy nine-figure fines for &#8220;divisional games.&#8221; The Unified Patent Court offers a single venue for clearing these families, but originators are countering with tactical bifurcation and opting out of classic patents. For stakeholders, the only defense is a granular, global view of the patent estate that treats IP as a quantifiable financial risk rather than a static legal right.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>FAQ<\/strong><\/h2>\n\n\n\n<p><strong>How exactly does filing a divisional application &#8220;reset&#8221; the clock?<\/strong><\/p>\n\n\n\n<p>A divisional application is treated as a separate filing and must undergo its own search and examination. If a competitor opposes the parent patent, that opposition has no direct legal effect on the divisional. Even if the parent is revoked, the competitor must start a new opposition against the divisional, which adds years to the process.<\/p>\n\n\n\n<p><strong>Why did the European Commission fine Teva for using a legal patent procedure?<\/strong><\/p>\n\n\n\n<p>The Commission found that while filing divisionals is legal, using them in a &#8220;staggered&#8221; way specifically to block competition and then withdrawing them to avoid a negative ruling constitutes an abuse of a dominant position under Article 102 TFEU.<\/p>\n\n\n\n<p><strong>What is the &#8220;Whack-A-Mole&#8221; strategy in pharmaceutical litigation?<\/strong><\/p>\n\n\n\n<p>This refers to a situation where a generic company successfully invalidates a patent, only to be met with another similar patent from the same family. Because divisionals can be filed as long as a parent is pending, the originator can keep &#8220;popping up&#8221; with new patents to maintain uncertainty.<\/p>\n\n\n\n<p><strong>What are the new EPO fees for divisionals in 2026?<\/strong><\/p>\n\n\n\n<p>Starting April 1, 2026, the EPO will charge \u20ac235 for a second-generation divisional and \u20ac480 for a third-generation divisional. These fees are in addition to the standard filing and search fees and are meant to deter companies from filing long chains of applications.<\/p>\n\n\n\n<p><strong>How does DrugPatentWatch help with &#8220;at-risk&#8221; launch decisions?<\/strong><\/p>\n\n\n\n<p>It provides a multi-country view of a drug&#8217;s patent estate, allowing companies to see if an originator has abandoned coverage in certain markets. It also maps the &#8220;layers&#8221; of a patent portfolio (compound, dosing, formulation) and provides data for risk-adjusted NPV models to see if a launch is financially viable despite pending divisionals.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Works cited<\/strong><\/h4>\n\n\n\n<ol class=\"wp-block-list\">\n<li>WIPO Study on Substantive and Procedural Requirements Regarding Voluntary Division of Patent Applications by Applicants, accessed March 29, 2026, <a href=\"https:\/\/www.wipo.int\/documents\/d\/scp\/docs-en-meetings-session-37-epo-1.pdf\">https:\/\/www.wipo.int\/documents\/d\/scp\/docs-en-meetings-session-37-epo-1.pdf<\/a><\/li>\n\n\n\n<li>Divisional applications under the European Patent Convention &#8211;
